Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

“Tis not the drinking that is to be blamed‚ but the excess”. Alcohol is an example of intoxicating drink. Society has viewed people who drink to excess as irresponsible‚ immoral‚ and of weak character. We know that alcohol has its consequences. At the same time‚ people don’t care and disregard its consequences. Alcohol drinking affects the way a person thinks‚ acts and feels. Many of us are at point in our life where we are searching for excitement and ways to fit in and have fun. For me‚ alcohol

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

To determine how changes in price and quantity influence market equilibrium one must first understand the relationship between demand curve and the supply curve. The amount of good or service that buyers can purchase is the quantity demanded‚ and the amount of good or service that sellers can sell is the quantity supplied. The demand curve depicts what occurs to the quantity demanded when its price changes while holding (income‚ price of related goods or services‚ taste‚ expectations‚ and

Market Equilibrium- Asifa Kwong Examine how market equilibrium is determined and explain why governments intervene in markets. Use diagrams to illustrate your answer. Equilibrium refers to the idea that there is no tendency to change‚ and market equilibrium is a situation where the price and the quantity supplied and the quantity demanded of a particular good are equal. The interaction between demand and supply can change the price mechanism which determines the prices and quantity of the goods

effects of competitive markets Economics 131 Introduction The degree to which a market or industry can be described as competitive depends in part on how many suppliers are seeking the demand of consumers and the ease with which new businesses can enter and exit a particular market in the long run (Makinaw‚ 2009). This paper will discuss the characteristics of a competitive market. This paper will also analyze the effects of competition amongst electronic chains with a focus on Circuit City

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a
