What is the main difference between physical and chemical changes versus nuclear changes? *
A. Nuclear changes do not involve the subparticles- protons, neutrons, or electrons.
B. Nuclear changes release less energy than chemical and physical changes.
C. Nuclear changes result in the formation of a different element while physical and
chemical changes involve the same elements from start to finish.
D. There are no differences.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

Hey can you me with this i really need y’all
