Chapter 4, Problem 42E

Write the balanced equation, then outline the steps necessary to determine the information requested in each of the following:

(a) The number of moles and the mass of chlorine, ${\text{Cl}}_2$, required to react with 10.0 g of sodium metal, Na, to produce sodium chloride, NaCl.

(b) The number of moles and the mass of oxygen formed by the decomposition of 1.252 g of mercury(II) oxide.

(c) The number of moles and the mass of sodium nitrate, ${\text{NaNO}}_{\text{3}}$, required to produce 128 g of oxygen. ( ${\text{NaNO}}_{\text{2}}$ is the other product.)

(d) The number of moles and the mass of carbon dioxide formed by the combustion of 20.0 kg of carbon in an excess of oxygen.

(e) The number of moles and the mass of copper(II) carbonate needed to produce 1.500 kg of copper(II) oxide. ( ${\text{CO}}_{\text{2}}$ is the other product.)

(f) The number of moles and the mass of formed by the reaction of 12.85 g of

with an excess of ${\text{Br}}_{\text{2}}$.
