Question

When an acetylene torch is used to weld metal an exothermic reaction occurs. Which is the balanced chemical equation for this reaction?

A. 2C2H2(g) + O2(g) → CO2(g) + 2H2O(g) + energy

B. 2C2H2(g) + O2(g) → 4CO2(g) + H2O(g) + energy

C. 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g) + energy

D. C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g) + energy

Answer 1

C

Answer 2

Here, only balanced equation is:

2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g) + energy

In short, Your Answer would be Option C

Hope this helps!
