    is considered in a state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by

    The movie Equilibrium directed by Kurt Wimmer‚ and the book 1984 written by George Orwell both explore what would happen when a government has complete control. When you let someone think for you and make all of your decisions‚ you lose what makes you human‚ which is your free will‚ and your ability to make conscious decisions. In both the text and movie they take away human identity to gain control. The key differences are the ways Big Brother and Father seize control‚ and what effect it has on

    cotton prices. The changes in cotton clothing market give us a good opportunity to illustrate the Principle of Market Equilibrium that any time there is an imbalance between supply and demand‚ economies will normally move toward an equilibrium in which no individual would be better off doing something else. In fact‚ we have now seen that a market tends to have a single price‚ the equilibrium price at which the quantity demanded of a good or service is equal to the quantity supplied. When the demand and/or

    main objective of this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the

    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

    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
