Question

If heat of combustion of methane is -890
kJ/mol, then amount of heat released when
13.2 g of CO2 is produced on combustion of
methane is​

Answer 1

Answer:

ANSWER

Heat of combustion for 1 mole of CO

2

is −393.5KJ

Number of moles in 35.2g of CO

2

=

44

35.2

=0.8mole

Thus heat of combustion for 0.8 mole of CO

2

is −393.5×0.8=−315KJ

Answer 2

heat of combustion of methane is -890

kJ/mol, then amount of heat released when

13.2 g of CO2 is produced on combustion of

methane is
