I used a stick of (vegan) butter as our example of thinking about how temperature changes the properties of something when it is wamer or cooler. 1. What is something else you could use to describe how temperature affects the properties of when it is warmer or cooler? How does this change whether it is warm or cold. Describe it.

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
