Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as

MAHATMA GANDHI vs. GENGHIS KHAN E.K ABSTRACT Leader is someone who has the ability to influence people on certain way. In order to become a leader‚ person has to have some skills or abilities. Through the history there many leaders with different characters‚ attributes‚ knowledge and skills. All of them had one common thing: they had ability to influence. Some leaders were better than the others‚ some left positive marks‚ some left negative ones and some left both of them. In this paper it

DISCUSSION Chemical equilibrium and its different applications were studied in this experiment. The Le Chatelier’s principle‚ which is the main principle behind chemical equilibrium‚ states that‚ “If an external stress is applied to a system at equilibrium‚ the system adjusts in such a way that the stree is partially offset as the system reaches a new equilibrium position.”[1] The “stress” can be a change in concentration‚ volume‚ pressure‚ or temperature that disturbs the equilibrium

Case in the news: Demand/Supply and Equilibrium This article is based on the fundamental idea of supply and demand of the iPhone 5 whose demand has outstripped its supply. Due to the fact that the demand is so high‚ even those who pre-ordered the new slim iPhone 5 had to wait until October to get this new phone. The sales have broken all previous records and stand tall at 2 million phones in the first 24 hours. According to the article people had been
