Most of Earth's atmosphere is made up of nitrogen gas. Nitrogen can also exist as a solid, liquid, or plasma. Four samples of nitrogen are each in a
different state but have the same mass. Which statement about the relative
amounts of thermal energy in the samples is true?

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 .
