AP* Chemistry CHEMICAL EQUILIBRIA: GENERAL CONCEPTS THE NATURE OF THE EQUILIBRIUM STATE: Equilibrium is the state where the rate of the forward reaction is equal to the rate of the reverse reaction. At these conditions‚ concentrations of all reactants and products remain constant with time once equilibrium has been established at constant temperature. (In stoichiometry‚ we dealt with equations that went to completion; often equilibrium equations are going to fall short of this goal.) Reactions are

Observations of Chemical and Physical Changes Derrick Davis Lab partner: None Location: My house Date Performed 25 Feb 15; 1600 CHE111-CO2 Photo 1 (Photo of me properly wearing safety goggles holding the student information card) Abstract: In chemistry it is important to understand the difference between physical and chemical changes. The objective of this experiment was to perform tests using heat or chemical mediators and observe the results for any physical or chemical changes. Various

1) 0.069 mol MgSO4/ 0.015 mol H2O = 4.6 = 5 Formulae for hydrated MgSO4 = MgSO4 5H2O 2) There are at least two reasons why heating to find percentage of water in hydrated crystals is not recommended for all hydrates. The first reason is that some hydrates have such a strong bond with the water that not all of it will be able to be removed. The second reason is that different hydrates have their own mass. Depending on the mass and type of hydrate‚ some of the molecule may be burned off from heating
