A mixture of cuso4 * 5H2O MgSO4 * 7H2O is heated until all the water is lost. If 5.020 g of the mixture gives 2,988 of the anhydrous salts, what is the percent by mass of cuso4 * 5H20 in the mixture?
Suppose the pH of the water is 4.67 and that the concentration of iron(II) in the water is 5.17x 10-5 M, what is the potential of the corrosion reaction under the above conditions at 298 K?
Consider reactions of the same Stoichiometry that are characterized by the following Kc values. Which reaction will have the smallest amount of product at equilibrium.
Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid.
