Chapter 21, Problem 40QP

Calcium oxide or quicklime $\left(\text{CaO}\right)$ is used in steelmaking, cement manufacture, and pollution control. It is prepared by the thermal decomposition of calcium carbonate:

${\text{CaCO}}_{\text{3}}(s)\to \text{CaO}(s)+{\text{CO}}_2(g)$

Calculate the yearly release of $\text{CO}$, (in kg) to the atmosphere if the annual production of $\text{CaO}$ in the United States is $1.7\times {10}^{10}$ kg.
