Although energy cannot be created or destroyed, energy can be transformed. Look at one type of energy transformation shown below:
chemical energy → heat energy → mechanical energy
Which of the following examples demonstrates this type of energy transformation?
F. O Charcoal is burned to heat the grill.
G.
Gasoline is burned to move a car.
H. A lamp is turned on to produce light.
J. Firewood is burned to toast marshmallows.

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 .
