Which of the following shows that the combustion of methane produces 802 kJ/mol of energy?
A. CH_(g) + 2O2(g) + 802 kJ/mol → CO2(g) + 2H2O(g)
B. CH4(9) +202(g) → CO2(g) + 2H20(9) - 802 kJ/mol
OC. CH4(9) +202(g) → CO2(g) + 2H2O(g) + 802 kJ/mol
D. CH4(g) + 20 (g)
802kJ
CO2(g) + 2H2O(9)

since electrons are negative the answer is neagtaive

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
