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 : The energy produced from the combustion of 5 mole is

Solution : Given,

Released energy = 803 KJ

The balanced combustion reaction is,

As per the question,

1 mole of releases energy = 803 KJ

5 mole of produced energy =

Therefore, the energy produced from the combustion of 5 mole is

if you mean hydrogen and oxygen then water is the product

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
