Answer: -

In the acetylene torch, 7.5 moles of Oâ‚‚ are needed to react with 3.00 moles of acetylene gas Câ‚‚Hâ‚‚.

Explanation: -

The balanced chemical equation for this reaction is

2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O

From the equation we see

2 moles of Câ‚‚Hâ‚‚ react with 5 moles of Oâ‚‚

3.00 moles of Câ‚‚Hâ‚‚ react with [tex] \frac{5 moles of O2}{2 moles of C2H2} [/tex] x 3.00 moles of Câ‚‚Hâ‚‚

= 7.5 moles of Oâ‚‚

Thus, in the acetylene torch, 7.5 moles of Oâ‚‚ are needed to react with 3.00 moles of acetylene gas Câ‚‚Hâ‚‚.
