Calculate the Heat Released (KJ)in the Reaction of 3 $\rarr$ C₂H₆(g)
Given:
2C₂H₂(g)+ 5O₂(g)

Calculate the heat released (kJ)in the reaction of 3.50 g of acetylene (C₂H₂)and excess hydrogen gas to form ethane gas:
C₂H₂(g)+ 2H₂(g) $\rarr$ C₂H₆(g)
Given:
2C₂H₂(g)+ 5O₂(g) $\rarr$ 4CO₂(g)+ 2H₂O(g), $\Delta$ H = -2320 kJ/mol
2C₂H₆(g)+ 7O₂(g) $\rarr$ 4CO₂(g)+ 6H₂O(g), $\Delta$ H = -3040 kJ/mol
2H₂(g)+ O₂(g) $\rarr$ 2H₂O(g), $\Delta$ H = -572 kJ/mol
