Answer to Question #114693 in General Chemistry for Kelvin

Question #114693

The heat of combustion of carbon in excess air is 3935 jmol-. Calculate the heat change when 60g of carbon undergoes complete combustion to produce carbon (iv) oxide ( C = 12, O = 16 )

Expert's answer

C+O₂=CO₂

3935 x 60 /12 = 19 675 j/mol = 19,675 kj/mol.
