The equation Ba + 2HNO3 -> Ba(NO3)2 + H2

1. Detailed information about the equation Ba + 2HNO₃ -> Ba(NO₃)₂ + H₂

• Ba is the chemical symbol for Barium, a metal with a valence of II.
• HNO3 is the chemical symbol for nitric acid, a strong acid.
• Ba(NO3)2 is the chemical symbol for barium nitrate, a salt of barium and nitric acid.
• H2 is the chemical symbol for hydrogen, a colorless, odorless gas.

In this chemical equation, one molecule of barium reacts with two molecules of nitric acid to form one molecule of barium nitrate and one molecule of hydrogen.

2. Reaction conditions

This reaction occurs when barium reacts with nitric acid under standard temperature and pressure conditions.

3. Reaction Process

The reaction process takes place when barium reacts with nitric acid to produce barium nitrate and hydrogen gas. When barium encounters the acid, it is oxidized and forms a barium ion Ba₂+. At the same time, the nitrate ion NO₃- from the nitric acid combines with the Ba₂+ ion to form barium nitrate. Meanwhile, two H+ ions from nitric acid combine to form hydrogen gas.

4. Observed phenomena

When barium reacts with nitric acid, the product barium nitrate is formed as a solution in water, while hydrogen gas escapes from the solution in the form of gas bubbles.
