In the balanced chemical reaction for the neutralization of calcium hydroxide with nitric acid, the coefficient of water is 2.

Nitric acid and calcium hydroxide as the reactants and calcium nitrate and water as the products.

$\bold {HNO_3+Ca(OH)_2 \rightarrow Ca(NO_3)_2+H_2O}$

To balance the equation take compounds and break down the atoms of each compound.

Reactants:

HNO3 has 1 H atom, 1 N atom and 3 O atoms

Ca(OH)2 has 1 Ca atom, 2 O atoms and 2 H atoms

Left side has a total of 3 H atoms, 1 N atom, 1 Ca atom, and 5 O atoms

Products:

Ca(NO3)2 has 1 Ca atom, 2 N atoms (1 x 2) and 6 O atoms (3 x 2)

H2O has 2 H atoms, and 1 O atoms

Right side has a total of 1 Ca atom, 2 N atoms, 7 O atoms, 2 H atoms

So, now put the numbers that make the number of atoms in each side equal.

$\bold {2HNO_3+Ca(OH)_2 \rightarrow Ca(NO_3)_2 + 2H_2O}$

Therefore, In the balanced chemical reaction for the neutralization of calcium hydroxide with nitric acid, the coefficient of water is 2.

Answer from: doughboy123

The answer to the question is letter a. 2

Explanation:

Write the formula of each compound

Calcium hydroxide = Ca(OH)₂

Nitric acid = HNO₃

Water = H₂O

Calcium nitrate = Ca(NO₃)₂

Chemical Reaction

Ca(OH)₂ + HNO₃ ⇒ Ca(NO₃)₂ + H₂O

Reactants Elements Products

1 Ca 1

1 N 2

3 H 2

5 O 7

Balanced Chemical Reaction

Ca(OH)₂ + 2HNO₃ ⇒ Ca(NO₃)₂ + 2H₂O

Reactants Elements Products

1 Ca 1

2 N 2

4 H 4

8 O 8
