Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Genetic drift and natural selection both play important roles in shaping the genetic makeup of a population in nature. Although this is true‚ they have different modes of doing so. Genetic drift‚ unlike natural selection‚ is a completely random process. While natural selection tends to improve the fitness of generations to come in the context of a certain environment‚ the chance events of genetic drift do not necessarily lead to forming positive environmental adaptions. In addition‚ the effects of

THERMAL EQUILIBRIUM AND TEMPERATURE Two systems are said to be in thermal equilibrium with each other‚ if they are at the same temperature. ZEROTH LAW OF THERMODYNAMICS It states that if two systems A and B are in thermal equilibrium with a third system C‚ then A and B must be in thermal equilibrium with each other. Fig. 1.01 shows two systems A and B separated by an adiabatic wall (a wall which does not allow hear flow).The two systems are placed in contact

Ethical drift is a concept of universal application to issues in health care management and leadership. Overt unethical behavior is always an issue‚ and one solved with a variety of policies and procedures. Ethical drift‚ however‚ is more invidious as it is often unseen until the real problems develop. In order to avoid ethical drift‚ it is necessary for the healthcare professional to first understand it: what it is and its causes. Only when the concept and causes of ethical drift are understood

judged. (Smith‚ 1944) Handy (1992) defined leadership as ‘A leader shapes and shares a vision which gives point to the work of others’. One such example is Sim Wong Hoo of Creative Technology. Sim Wong Hoo as a Transformational Leadership He is considered a transformational leadership based on Dexter Dunphy and Doug Stace (1990). He had a vision of selling 100 million units of something back when Creative was only a tiny little company. He knew that people would make fun of him for his ridiculous

Continental Drift and Plate Tectonics Theory (Part 1a) Introduction: The Beginning of the “Continental Drift Theory” In the middle of the eighteenth century‚ James Hutton proposed a theory‚ uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg‚ 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham

“The Fast and the Furious: Tokyo Drift” by Justin Lin is a film that allows viewers to attain a heightened level of understanding of the concept of belonging. It extensively explores the notions of separation‚ connection‚ displacement and acceptance throughout varying contexts to demonstrate that belonging carries different meaning to individuals. From the beginning it is evident to the audience that the main character‚ Sean‚ is no stranger to displacement as his mother states “This is our third

offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents‚ and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically‚ a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population‚ isolation from other populations‚ no net mutations
