Check Your Progress You have returned home from practice and there is a note on the fridge that says:
“There’s pizza in the fridge, reheat in the microwave if you’re hungry.”
You put the pizza in the microwave and pour yourself a glass of lemonade while you wait. The microwave beeps, and you pull the hot pizza out and set it on the counter. As you set the pizza down, you accidently knock your lemonade over. It takes you a few minutes to clean up the mess, so when you finally come back to the pizza, it is cool.
Draw a molecular model of the pizza as it cools. Include a written explanation.
Be sure to include in your model:
An arrow showing overall (macroscopic) energy movement
Air molecules with motion arrows
Pizza molecules with motion arrows
Collisions between the two molecule types
In your explanation, include the following words: collision(s), temperature, energy

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 .
