2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.

Chem 141, Dr. Haefner 2. (a) Many main group oxides form acidic solutions when added to water. For example solid tetraphosphorous decaoxide reacts with water to produce phosphoric acid. Write a balanced chemical equation for this reaction. (b) Calcium phosphate reacts with silicon dioxide and carbon graphite at elevated temperatures to produce white phosphorous (P4) as a gas along with calcium silicate (Silcate ion is SiO3²-) and carbon monoxide. Write a balanced chemical equation for this reaction.
