Chapter 2, Problem 21P

For each of the following chemical reactions, calculate the mass of the underlined reactant that is required to produce 1.000 g of the underlined product.

(a) $\underset{\_}{\text{Mg}}+\text{2 HCl}\to \underset{\_}{{\text{H}}_{\text{2}}}+{\text{MgCl}}_{\text{2}}$

(b) $\text{2}\underset{\_}{{\text{CuSO}}_{\text{4}}}+\text{4KI}\to \text{2CuI}+\underset{\_}{{\text{I}}_{\text{2}}}+{\text{2K}}_{\text{2}}{\text{SO}}_{\text{4}}$

(c) $\underset{\_}{{\text{NaBH}}_{\text{4}}}+{\text{2H}}_{\text{2}}\text{O}\to {\text{NaBO}}_{\text{2}}+\underset{\_}{{\text{4H}}_{\text{2}}}$
