GED Study Guide for Chemistry

GED Study Guide for Chemistry The GED, or General Education Development Test, is taken in the U.S. or then again Canada to exhibit capability in secondary school-level scholarly abilities. The test most generally is taken by individuals who didn't finish secondary school or get a secondary school recognition. Passing the GED awards a General Equivalency Diploma (likewise called a GED). One segment of the GED covers science, including science. The test is various decision, drawing on ideas from the accompanying territories: The Structure of MatterThe Chemistry of LifeProperties of MatterChemical Reactions The Structure of Matter All substances comprise of matter. Matter is anything which has mass and occupies room. Some significant ideas to recall aboutâ matterâ are: Matterâ is comprised of at least one of more than 92 normally occurring elements.Each element is an unadulterated substance, comprised of just one sort of atom.An atom consists of three kinds of particles:â protons,â neutrons, andâ electrons. A molecule doesn't have to have each of the three particles, however will consistently contain in any event protons.Electrons are negatively chargedâ particles,â protonsâ have a positive charge, andâ neutronsâ do not have an electrical charge.An iota has an inward center called aâ nucleus, which is the place the protons and neutrons are found. The electrons circle around the outside of the nucleus.Two fundamental powers hold iotas together. Theâ electric forceâ holds the electrons in circle around the core. Inverse charges pull in, so the electrons are attracted to the protons in the core. Theâ nuclear forceâ holds the protons and neutrons together inside the core. The Periodic Table Theâ periodic tableâ is a graph which sorts out the compound components. The components are sorted by the accompanying traits: Nuclear Numberâ -number of protons in the nucleusAtomic Massâ -aggregate of the quantity of protons in addition to neutrons in the nucleusGroup -sections or different segments in the occasional table. Components in a gathering share comparable compound and physical properties.Period -columns from left to directly in the period table. Components in a period have a similar number of vitality shells. Matter can exist as an unadulterated component, yet mixes of components are progressively normal. Moleculeâ -a particle is a mix of at least two iotas (could beâ fromâ the same or various components, for example, H2â or H2O)Compound -a compound is a mix of two or moreâ chemically-bondedâ elements. For the most part, mixes are viewed as a subclass of atoms (a few people will contend they are controlled by the kinds of synthetic bonds). Aâ chemical formulaâ is a shorthand method of indicating the components contained in an atom/compound and their proportion. For instance, H2O, the concoction recipe for water, shows that two particles of hydrogen consolidate with one iota of oxygen to shape an atom of water. Synthetic bonds hold iotas together. Ionic Bondâ -shaped whenâ an electron transfersâ from one iota to anotherCovalent Bondâ -framed when two particles share at least one electrons The Chemistry of Life Life on earth relies upon the synthetic elementâ carbon, which is available in each living thing. Carbon is so significant, it shapes the reason for two parts of science, organicâ chemistryâ and natural chemistry. The GED will anticipate that you should be acquainted with the accompanying terms: Hydrocarbonsâ -particles that just contain the components carbon and hydrogen (e.g., CH4 is a hydrocarbon while CO2 is not)Organic -alludes to the science of living things, all of which contain the component carbonOrganic Chemistryâ -investigation of the science of carbon mixes engaged with life (along these lines, contemplating jewel, which is a crystalline type of carbon, isnt remembered for natural science, however concentrating how methane is delivered is secured by natural chemistry)Organic Moleculesâ -atoms that have carbon iotas connected together in an orderly fashion (carbon chain) or in a roundabout ring (carbon ring)Polymer -hydrocarbons which have anchored together Properties of Matter Periods of Matter Each period of issue has its own synthetic and physical properties. The periods of issue you have to know are: Solidâ -a strong has a clear shape and volumeLiquid -a fluid has a definiteâ volumeâ but can change shapeGas -the shape and volume of a gas can change Stage Changes These periods of issue can change starting with one then onto the next. Recall the meanings of the accompanying stage changes: Meltingâ -dissolving happens when a substance changes from a strong to a liquidBoiling -bubbling is the point at which a substance changes from a fluid to a gasCondensing -buildup is whenâ a gas changesâ to a liquidFreezing -freezing is whenâ a fluid changesâ to a strong Physical Chemical Changes The progressions that occur in substances might be categorizedâ inâ two classes: Physical Changeâ -doesn't deliver another substance (e.g., stage changes, squashing a can)Chemical Changeâ -produces another substance (e.g., consuming, rusting, photosynthesis) Arrangements An answer comes about because of joining at least two substances. Causing an answer for can deliver either a physical or compound change. You can reveal to them separated thusly: The first substances can be isolated from each other if the arrangement creates just a physical change.The unique substances can't be isolated from each other if a concoction change occurred. Synthetic Reactions Aâ chemical reactionâ isâ the processâ that happens when at least two substances consolidate to create a synthetic change. The significant terms to recall are: synthetic equationâ - nameâ was givenâ to the shorthand used to portray the means of a concoction reactionreactantsâ -the beginning materials for a compound response; the substances that consolidate in the reactionproductsâ -the substances that are framed because of a substance reactionchemical response rateâ -the speed at which a compound response occursactivation energyâ -the outside vitality that must be included request for a concoction response toâ occurcatalystâ -a substance that encourages a compound response to happen (brings down the enactment vitality), yet doesn't take an interest in the response itselfLaw of Conservation of Massâ -this Law expresses that issue is neither made nor annihilated in a concoction response. The quantity of reactant iotas of a compound response will be equivalent to the quantity of item particles.

IT metrics Essay Example | Topics and Well Written Essays - 750 words

IT measurements - Essay Example The monetary estimation of IT to an organization will in general rely upon the specific business needs of the organization under core interest. Extensively, IT will in general add to four significant regions in almost all organizations. These zones incorporate the corporate market position and income age; client care for business activities; immediate and backhanded monetary advantages, for example, cost reserve funds; and interests in IT that improve the business tasks through worth expansion. Contingent upon the idea of the business in center, it is relevant to quantify the estimation of IT commitment as needs be. It has been proposed that IT’s commitment to financial worth can be estimated most viably considering the nonappearance of the significant IT administrations to a business (Sliger and Broderick, 2008). The monetary estimation of IT to a business can be estimated best while thinking about what might occur on the off chance that IT administrations and products were e xpelled. Despite the fact that this may appear to be an extraordinary technique for evaluation, it gives the most practical situation. Likewise, organizations should concentrate on zones that issue most -, for example, the conveyance of merchandise to clients in the wake of booking. This permits organizations to perceive how IT adds to the pattern activities and lets the business acknowledge how IT framework would expand incomes best. The execution of IS in a business activity is to guarantee that security breaks can't influence the whole business activity contrarily. Measuring the profits gave by IS to a business tasks condition may not be basic at all.... This permits organizations to perceive how IT adds to the pattern activities and lets the business acknowledge how IT framework would enlarge incomes best. IS Value Assessment Models The usage of IS in a business activity is to guarantee that security penetrates can't influence the whole business activity adversely. Measuring the profits gave by IS to a business tasks condition may not be straightforward by any stretch of the imagination. From one perspective, there are organizations that are executing secure data, for example, charge card numbers utilizing IT; then again, there are organizations that are doing minimal more than giving client care on the web. Utilizing comparable strategies to quantify IS esteem expansion for different organizations is profoundly unreasonable so different models are set up that depend in enormous part on the idea of the business being referred to. It is suggested that organizations characterize in detail what regions are to be esteemed most as far as security. The explanations for such worth expansion grouping ought to likewise be elucidated dependent on esteem expansion to business activities. When such worth expansion zones have been indicated, the following stage ought to be to order IS esteem expansion (Tsiakis and Pekos, 2008). Appropriateness of Traditional Financial Ratios and Measurements Traditional monetary proportions and estimations can't be applied to IT and IS legitimately, yet rather, they require some control before they can be applied. It is relevant to take note of that monetary proportions and estimations are not completely pertinent to various distinctive IT and IS zones, for example, the arrangement of data transfer capacity, infection location rates, and so on. In any case, this doesn't show that financial proportions and

Modelling Operational Risk by AMA Essay Example | Topics and Well Written Essays - 1250 words

Demonstrating Operational Risk by AMA - Essay Example Lavin and Scherrish (1999) focused on that these measurable methods are constantly communicated as the arbitrary vector of information dependent on chance cells that have indicated thickness for a given vector of the parameter. Â Shevchenko (2011) related that Bayesian induction to various focal points, for which they are utilized to display operational hazard. An ordinary case of this is the thing that Embrechts and Puccetti (2008) noted to be the consistency and accommodation related with the factual system utilized in evaluating vulnerabilities. As a quantitative methodology, the results with Bayesian derivation are constantly destined to be the equivalent at whatever point the comparative factors are utilized. This makes the results with Bayesian surmising exceptionally solid and predictable among a comparative arrangement of operational factors inside a bank (Lambrigger, Shevchenko, and Wã ¼thrich, 2007 and Neil, Fenton and Tailor, 2005). In addition, Shevchenko (2011) recognized the way that the Bayesian surmising is exceptionally obliging and flexible as it joins master feelings with recorded interior and outside information utilized in different operational hazard estimations (Burnecki, Kukla and Taylor, 2005). Â Even however the Bayesian deduction has a few qualities and focal points for use, Shevchenko (2010) regretted that the approach’s over-dependence on situation examination and master judgment goes about as a significant mishap for utilization inside a decent number of firms. Adding to this, Wasserman (1997) and Alderweireld, Garcia and Lã ©onard (2006) concurred that despite the fact that both situation examination and master judgment give significant data to estimating and dynamic, keeps money with the generally constrained dataset and those that solitary began a business might not have enough of these to utilize the Bayesian derivation.

Learn about our Wellness Board Amy Morin, LCSW on October 23, 2019 How Stress Impacts Your Health Overview Signs of Burnout Stress and Weight Gain Benefits of Exercise Stress Reduction Tips Self-Care Practices Mindful Living Jakob Helbig / Getty Images When people face stress, many find that the stress can compound with thoughts of not only the present stress but about events or issues that occurred in the past or even events that may occur in the future. If youve experienced this kind of stress, you may have noticed that the same thoughts replay over and over again in your mind creating an endless loop and increased worry. This thought pattern not only does nothing to help solve the problems at hand, and but it can also interfere with healthy practices that can help create inner peaceâ€"like restful sleep. The solution is to clear your mind and give yourself a break from these recurring, compounding stressors. With a refreshed approach, you may be able to solve your problem or at least compromise on a solution that is manageable. Positive Effects of Clearing Your Mind The process of replaying the same thoughts over and over in your head is known as rumination. Research has shown that rumination can be harmful in many ways?? and that being able to clear your mind and free yourself from the negative practice is an important skill to master. One of the main problems with rumination is that when you focus on disturbing events in the past or future, you create anxiety for yourself in the present. This anxiety triggers your stress response and robs you of joy in the moment. The result may be chronic stressâ€"an unhealthy condition that can lead to a host of physical, mental, and emotional problems. By learning to avoid rumination (or manage it successfully), you may be able to maintain or achieve an improved state of mind. Better Rest Rumination has been found to affect rest.?? Not only does rumination delay the time at which you stop stressing about, say, work and start relaxing at the end of the day, but it can affect your sleep as well. With less time to rejuvenate and more time feeling unpleasant, those who ruminate get a double-dose of stress with limited ability to recover. By managing rumination better, you may be able to spend more time (both awake and asleep) in a more restful state. Decreased Cortisol Chronic stress, which is exacerbated by rumination, is thought to contribute to illness through the over-activation of stress-responsive biological systems. Rumination may also alter the body’s stress-responsive systems by amplifying and prolonging exposure to physiological mediators, such as cortisol.?? Cortisol is a hormone that is released by the adrenal glands and is commonly known as the stress hormone. Cortisol plays several important roles in the body that can affect the way you feel. For example, it can help to control blood sugar levels, regulate metabolism, reduce inflammation, and assist with memory formulation. But prolonged high levels of cortisol are associated with negative health outcomes. One study found that those who engaged in rumination had a higher level of cortisol in their system by the end of the day, but not higher levels at the beginning, pointing to the likelihood that the cortisol was linked to their way of handling the days stresses.?? The study also demonstrated that rumination (not just the events of the day) is directly related to increased physical responses to stress. Improved Creativity Rumination can kill your creativity. One study found that those who ruminated about problems at work were less creative on the job, while those who engaged in problem-solving thinking showed quicker recovery off the job.?? In short, ruminating more often probably means that you take your work home with you. On the other hand, those who participate in problem-solving thoughts are likely to be more creative (and likely more effective) on the job and enjoy more relaxed recovery after work. Other research has also linked rumination with a decreased ability to see solutions to problems, which can potentially lead to more stress.?? How to Clear Your Mind Clearing your mind can help combat rumination and may lead to better sleep, more effective downtime after work, greater focus, and increased creativity. The practice may even be good for your relationships. So investing some time in mind-clearing strategies is well worth it. If your thoughts about a stressful situation become stuck and thinking about an event no longer leads to positive change, it’s time to take steps to clear your mind. Of course, letting go of negative emotions is easier said than done. There are methods, however, that you may be able to use to quiet your mind and enjoy what life has to offer in the present moment. Meditate Research shows that meditation can be helpful in facilitating forgiveness,?? letting go of rumination, and reducing negative emotions. Meditation provides many other benefits, as well. To start a meditation practice, simply find a place where you can sit and relax. Then observe your thoughts without becoming attached to them. Once you’ve noticed them, let them go and bring your focus back to the present moment. How to Practice Basic Meditation Cultivate Mindfulness Mindfulness is the practice of becoming fully immersed in an activity, rather than in your thoughts about other things.?? Mindfulness is a great option for busy people. While it involves slowing down and focusing on one thing, it doesn’t involve stopping all activity the way traditional meditation does. Completing one activity with mindfulness can be a restorative way to clear your mind and get things done. Try cleaning a room, clearing out a closet, or cooking a healthy meal. How to Practice Mindfulness in Your Life Engage in Expressive Writing If your mind is filled with stressful feelings, it may be helpful to give in to the thoughts and express them through writing. Journaling allows you to delve deeper into the topics that plague your thoughts. By fully experiencing and examining your emotions, you may be able to brainstorm solutions and examine different ways of looking at your problems (a technique known as cognitive restructuring). When you first begin, set a time limit so you don’t get stuck in rumination. Multiple studies have found that 20 minutes is an effective amount of time for positive mental and emotional change without sliding into rumination.?? Journaling for Effective Stress Management Distract Yourself Sometimes, the best thing you can do to clear your mind is to change your focus. Get out and exercise with a friend. Get involved with a project or hobby. Lose yourself in a good book for a few minutes. Activities such as tai chi and karate can also be used to clear your mind. The simple act of distraction is an excellent way to bring positive activities into your life and take a break from stress and worry.?? Connect With Friends You may have noticed that when youre overly stressed and entrenched in rumination, youre not as much fun to be around. As a result, your relationships may suffer. Conversely, focusing on positive relationships can minimize stress and the tendency to ruminate. By strengthening your relationships, you provide yourself with a healthy coping technique. Research has found that those with strong social connections tend to use rumination less to cope with stress. These people also have lower rates of depression, post-traumatic stress disorder, and stress-linked inflammatory responses.?? Processing your problems with an empathetic friend can be a healthy distraction and a highly effective coping method. But even if you choose not to discuss your problems, the simple act of getting together can be useful to clear your mind. Its a fun and healthy way to deal with stress and anxiety. Avoid Ruminating One danger to watch for is the potential for co-rumination. Co-rumination involves continually revisiting and talking about problems with friends.?? This type of behavior can lead to negative feelings and exacerbate feelings of anxiety and depression. Talking to friends can be an important outlet, but it is important to remember that not all forms of support are necessarily helpful. Healthy emotional processing involves thinking about things realistically, often finding ways to solve problems or find the positives. Rumination typically involves repetitive thoughts that only focus on the negative. If you find yourself dwelling only on the negative when talking to a friend, its likely that you are engaging in non-helpful co-rumination. Look for ways to process your feelings and find support without slipping into rumination and negative thinking. How To Think Through Stress and Not Obsess
