Question

Which of the following shows that the combustion of methane produces 802
kJ/mol of energy?
A. CH4(9) +202(g) + 802 kJ/mol + CO2(g) + 2H2O(g)
B. CH4(9) +202(g) → CO2(g) + 2H2O(g) - 802 kJ/mol
C. CH4(9) + 202(g) → CO2(g) + 2H2O(g) + 802 kJ/mol
802kJ
O D. CH4(9) +202(9)
CO2(g) + 2H2O(g)

Answer 1

Answer: hewo, there! your answer is Below

CH4(g) + 2O2(g) CO2(g) + 2H2O(g) + 802 kJ/mol

Explanation:

Hope this helps!!!

Have a great day!!!

Answer 2

The reaction $CH_{4} (g)+2O_{2}$ → $CO_{2}(g) +2H2_{O} (g)+802kJ/mol$

shows combustion reaction of methane in which energy 802 KJ/mol energy produces.

What is combustion reaction?

A combustion reaction occurs when a substance combines with oxygen gas and produces energy in the form of light and heat. One of the reactants in combustion reactions must be oxygen. Water vapor is produced when hydrogen gas is burned.

It can be seen that this reaction give carbon di-oxide and water hence, combustion reaction will show this reaction.

$CH_{4} (g)+2O_{2}$ → $CO_{2}(g) +2H2_{O} (g)+802kJ/mol$

the correct answer will be option (c).
