Sabrina and Harvey are ready to perform their experiment. They created a machine that pours the same amount of liquid on a rock each day. Sabrina fills her machine with water. Harvey fills his machine with a solution of water and acid. They place the same type of rock in each machine for a year. What do you think will happen?

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 .
