Hydrochloric acid (HCI) is a strong acid and Acetic acid (HC2H302) is a weak acid. Explain in terms of percent ionization, why these acids are classified as such.

1. Strong acids completely ionize
2. Weak acids completely ionize
3. Strong acids do not completely ionize
4. Weak acids do not completely ionize

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 .
