Question

The combustion of 1 mol ch4 releases 803 kj of energy. how much energy is produced from the combustion of 5.00 mol ch4.

Answer 1

Answer : The energy produced from the combustion of 5 mole
`CH_4` is
`4015KJ`

Solution : Given,

Released energy = 803 KJ

The balanced combustion reaction is,

`CH_4+2O_2\rightarrow CO_2+2H_2O`

As per the question,

1 mole of
`CH_4` releases energy = 803 KJ

5 mole of
`CH_4` produced energy =
`(5mole)/(1mole)* 803KJ=4015KJ`

Therefore, the energy produced from the combustion of 5 mole
`CH_4` is
`4015KJ`
