Question 1

​In a chemical equation, the _________ are written on the left side of the arrow, and the _________ are written on the right side of the arrow.


Question 2

In a metallurgical process the mineral pyrite, FeS2, is roasted in air:

           FeS2 + O2→ Fe2O3 + SO2

The SO2 is then converted into H2SO4 in the following reactions:

           2SO2 + O2→ 2SO3

              SO3 + H2SO4→ H2S2O7

              H2S2O7 + H2O → 2H2SO4

Assuming the mineral is 24.0% FeS2 and the remainder is inert, what mass of H2SO4 is produced if 155 g of the mineral is used?
