qwelly [4]

Answer:

7mol of CO2

Explanation:

The balanced equation for the combustion of acetylene is

$2C_{2} H_{2}+5O_{2}=4CO_{2}+2H_{2}O$

Using the equation coefficients, we can find out the number of moles of CO2 produced as follows.

$\frac{3.5mol C_{2}H_{2}}{1} *\frac{4CO_2}{2 C_{2}H_{2}} =7molCO_{2}$
