Consider the reaction:

$C{O}_2+4HC{H}_{2}O+H_{2}O$

Suppose $1\mathrm{.}81$gCO$2$ and $0\mathrm{.}057gH$ are fed to the reactor.

a$)$ What is the limiting reactant? What is the excess reactant?

b$)$ Find the maximum $C{H}_{2}O$ produced in grams?

c$)$ If actually $0\mathrm{.}012gC{H}_{2}O$ is obtained from the reaction medium. What is the percent yield?
