Question

Calculate the amount of heat that is produced when 5 kg of Hydrogen, Methane, Methanol and Dimethyl Ether is burned?

Answer 1

Answer:

It is given that when 10 g of methane is burnt in oxygen, the heat evolved is 560 kJ.

Number of moles of methane =

16

10

=0.625 mol

For 10 g of methane, the heat evolved is 560 kJ and so, for 16 g of methane, the heat evolved will be =

10

560

×16=896 kJ

Hence, the heat of combustion of methane is 896 kJ/mol.
