1) Combustion of acetylene is exothermic reaction 

2) The balanced chemical reacting combustion of acetylene is C₂ H₂ + 5O₂ → 2CO₂ +H₂ O

3) 2 moles of water produced 2 moles of acetylene reacts 

4) 44 g of CO₂ produced when of acetylene reacts

Answer 1

2) The balanced chemical reacting combustion of acetylene is C₂ H₂ + 5O₂ → 2CO₂ +H₂ O
