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.

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.
