The gaseous hydrogen acetylene, C2H2 used in welder’s torches, relea

1.	The gaseous hydrogen acetylene, C2H2 used in welder’s torches, releases 1300 KJ, when 1 mole of C2H2 undergoes combustion, then which of the following is not true? 1) combustion of acetylene is an exothermic reaction 2) the balanced chemical reaction of combustion of acetylene is C2 H2 + 5O2 → 2CO2 + H2O3) 2 moles of water produced when 2 moles of acetylene reacts 4) 44 g of CO2 produced, when 13 g of acetylene reacts
Answer» 2) the balanced chemical reaction of combustion of acetylene is C₂ H₂ + 5O₂→ 2CO₂ + H₂O 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O is a balanced chemical reaction.
