Include the states of matter See Hint Part 2 What is the value of kJ

Explanation / Answer

1.

The over all reaction is ,

2 CH4 (g) + 4 O2 (g) -------------> 2 CO2 (g) + 4 H2O (g)

For having lowest numeric coefficients, divide the entire equation by 2

(Z):

CH4 (g) + 2 O2 (g) ----------> CO2 (g) + 2 H2O (g)

2.

deltaHz = ( - 1038 - 566 ) / 2 = - 802 kJ
