Answer 2

I can help you with completing the equations of the corresponding reactions. Here are the answers:

a) S + O2 = SO2 This is a synthesis reaction, where two elements combine to form a compound. The product is sulfur dioxide, a colorless gas with a pungent odor.

b) Fe + Cl2 = FeCl2 This is also a synthesis reaction, where iron reacts with chlorine gas to form iron(II) chloride, a greenish solid. Iron has a variable oxidation state and can form two types of chlorides: FeCl2 and FeCl3. In this case, iron has a lower oxidation state of +2.

c) SO2 + H2O = H2SO3 This is a combination reaction, where sulfur dioxide reacts with water to form sulfurous acid, a weak acid that can act as a reducing agent. Sulfurous acid is unstable and decomposes into sulfur dioxide and water when heated.
