pipeline welders use ethyne (acetylene) as a fuel for “cutting torches.” the balanced equation for the combustion of acetylene is 2 c₂h₂(g) + 5 o₂(g) → 4 co₂(g) + 2 h₂o(g)\nthe energy conversion that occurs during this reaction is from\n9. a. chemical to thermal energy\nb. electrical to thermal energy\nc. thermal to mechanical energy\nd. electromagnetic radiation to chemical energy\na.

Answer

Brief Explanations:

Combustion reactions release heat. In the combustion of acetylene, chemical - bonds in acetylene and oxygen are broken and new bonds are formed in carbon - dioxide and water, releasing thermal energy. So the energy conversion is from chemical to thermal energy.

Answer:

A. chemical to thermal energy
