UkoKoshka [18]

<u>Answer:</u> 1.2 moles of carbon dioxide is produced for the given value of oxygen.

<u>Explanation:</u>

The chemical reaction for the combustion of acetylene follows the equation:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

By stoichiometry of the reaction:

5 moles of oxygen produces 4 moles of carbon dioxide.

So, 1.5 moles of oxygen will produce = \frac{4}{5}\times 1.5=1.2mol of carbon dioxide.

Hence, 1.2 moles of carbon dioxide is produced for the given value of oxygen.
