<u>Answer:</u> The balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.
<u>Explanation:</u>
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The balanced chemical equation for the reaction of nitric acid and calcium hydroxide follows:

By Stoichiometry of the reaction:
2 moles of nitric acid reacts with 1 mole of calcium hydroxide to produce 1 mole of calcium nitrate and 2 moles of water molecule.
Hence, the balanced chemical equation for the reaction of nitric acid and calcium hydroxide is written below.

The answer is D."We see whole images, while feature detectors detect specific"
Shatter into tiny pieces
The crystal may break due to the fall.
<span>the molar mass of a compound is the sum of the products of the atomic masses by the number of atoms of the element.
molar mass of Na</span>₂SO₄<span> is - 142 g/mol.
1 mol of </span>Na₂SO₄<span> has a mass of 142 g.
In 1 mol of </span>Na₂SO₄<span> the mass of Na is 23 g/mol x 2 = 46 g.
Mass of Na in 1 mol of </span>Na₂SO₄ is - 46 g
mass of Na in 0.820 mol of Na₂SO₄ - 46 g /1 mol x 0.820 mol = 37.72 g.
mass of Na is 37.72 g
