present: 24.19 g C, 4.06 g Hand 26.75 g 0.
You won't be able to enter subscripts, so just enter the number where it goes.
For example, S203.
Your formula should have the following order of atoms: CHO

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 .
