This thermochemical equation describes the reaction of nitrogen monoxide with
oxygen to produce nitrogen dioxide. 2NO(g) + O2(g) –> 2NO2(g) AH = -114 kJ
Which statement best describes the energy change that occurs when 1.0 mol of
NO2(g) is produced by this reaction? *

i think it's c. i'm not sure but i think so.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
