Answer 1

2 HNO3
2 H2O
...........

Answer 2

Balancing the Chemical Equation

To balance the chemical equation Ba(OH)2 + HNO3 => Ba(NO3)2 + H2O, we need to ensure that the same number of each type of atom is present on both sides of the equation.

Step-by-Step Balancing:

1. Counting Atoms: - Ba: 1 (left), 1 (right) - O: 2 (left), 3 (right) - H: 2 (left), 2 (right) - N: 1 (left), 2 (right)

2. Balancing: - Start by balancing the elements that appear only once on each side of the equation. In this case, we can balance the barium (Ba) and the nitrogen (N) first.

3. Balancing Ba: - Add a coefficient of 1 in front of Ba(OH)2 and Ba(NO3)2 to balance the barium atoms.

4. Balancing N: - Add a coefficient of 2 in front of HNO3 to balance the nitrogen atoms.

5. Balancing O and H: - After balancing Ba and N, the oxygen (O) and hydrogen (H) atoms will automatically be balanced due to the nature of the compounds involved.

Balanced Chemical Equation:

Ba(OH)2 + 2HNO3 => Ba(NO3)2 + 2H2O

This balanced equation ensures that the same number of each type of atom is present on both sides of the chemical equation.
