Sodium sulphate chemically reacts with barium chloride in the form of their aqueous solution to form a white precipitate of barium sulphate. This reaction is a chemical change, as the products are entirely different from the reactants in chemical composition and chemical properties. Simulator Procedure
The main chemical concept that this lab involves is the Law of Conservation of Mass. This states that in a chemical reaction, matter can neither be created or destroyed, or more simply, the mass of the products must equal the mass of the reactants.
Lab 2: Carbohydrates and Protein/Lipid Laboratory 2, AP Biology 2011 Spurthi Tarugu, Kavinmozhi Caldwell, Chelsea Mbakwe, Radha Dave, Navya Kondeti Abstract: Almost all living organisms contain four organic compounds, two of which are lipids and proteins.
Heating magnesium in the presence of air causes the metal to ignite and burn- lots of light and heat are given off and a new compound is obtained. According to the law of conservation of mass, the total mass of the products of a chemical reaction must equal the mass of the reactants.

Oct 06, 2002 · Where K w is the equilibrium constant for water at 25° C (unitless) [H +] is the molar concentration of hydrogen [OH-] is the molar concentration of hydroxide. An equilibrium constant less than one (1) suggests that the reaction prefers to stay on the side of the reactants -- in this case, water likes to stay as water. Process advancement in chemistry and chemical engineering research...Jun 09, 2015 · Stoichiometry is the technique of using the molar ratios in balanced chemical equations to calculate the amount of reactants or products. In this lab a sample of sodium carbonate (Na 2 CO 3) with a mass of 4 - 5 g is dissolved in distilled water. Using distilled water reduces the chance that any excess carbonate ions may be present.
