# If 4.36 moles of C5H12 reacts with excess O2, how many moles of CO2 will be produced in the following combustion reaction?

## C5H12 + 8O2 -----> 6H2O + 5CO2

$21.80$ moles

#### Explanation:

${C}_{5} {H}_{12} + 8 {O}_{2} \rightarrow 6 {H}_{2} O + 5 C {O}_{2}$

From the equation, we see that 1 mole of ${C}_{5} {H}_{12}$ reacts with excess of ${O}_{2}$ to produce $5$ moles of $C {O}_{2.}$

So, $4.36$ moles of ${C}_{5} {H}_{12}$ will react with excess ${O}_{2}$ to produce
$\left(4.36 \cdot 5\right)$ moles$= 21.80$ moles.

That's it .
