Acetylene (C2H2) gas is often used in welding torches because of the very high hear produced when it reacts with oxygen (O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of carbon dioxide produced by the reaction of 2.3 mol of acetylene. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

To solve this, we first need to write the balanced chemical equation for the combustion of acetylene (C₂H₂) with oxygen (O₂):

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

This equation shows that 2 moles of acetylene (C₂H₂) produce 4 moles of carbon dioxide (CO₂).

Next, we'll use stoichiometry to find the number of moles of CO₂ produced by 2.3 moles of C₂H₂:

\[
\frac{4 \, \text{mol} \, CO_2}{2 \, \text{mol} \, C_2H_2} = 2 \, \text{mol} \, CO_2 \text{ per mol of } C_2H_2
\]

Now, multiply by the given number of moles of C₂H₂:

\[
2.3 \, \text{mol} \, C_2H_2 \times 2 = 4.6 \, \text{mol} \, CO_2
\]

Therefore, the reaction produces **4.6 moles of carbon dioxide (CO₂)**.
