In the balanced chemical reaction for the neutralization of calcium hydroxide with nitric acid, HNO3, the coefficient of water is In the balanced chemical reaction for the neutralization of calcium hydroxide with nitric acid, HNO3, the coefficient of water is:. a. 2 b. 1 c. 3 d. 4

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.

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.      

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