Question

How much heat is released by the combustion of 2 mol of methane?

A.-80.3 kJ
B.-802.5 kJ
C.-1,605.1 kJ
D.-6,420.3 kJ

Answer 1

The answer to how much heat is released would be c -1,605.1

Answer 2

C) 1,605.1kJ

Step-by-step explanation:

Combustion of methane (CH4) is known to be an exothermic reaction. 802.3kJ/mol CH4 (50.1kJ/g) of heat is released during combustion.

If 2 mol of CH4 is combusted

2 × 802.3kJ = 1,604.6kJ of heat is released

1,604.6 ≈ 1605.1kJ
