Hey there!

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + H₂O

Balance O. (not including SO₄)

2 on the left, 1 on the right. Add a coefficient of 2 in front of H₂O.

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + 2H₂O

Balance H.

4 on the left, 4 on the right. Already balanced.

Balance SO₄. (polyatomic ion)

1 on the left, 1 on the right. Already balanced.

Balance Mg.

1 on the left, 1 on the right. Already balanced.  

Our final balanced equation:

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + 2H₂O

So your answer is a. 1, 1, 1, 2.

Hope this helps!

earnstyle [38]

The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:

Sodium hydroxide + Sulfuric acid →  Sodium sulfate +water

<h3>What is the balanced molecular equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

In the given reaction, the reactants have been sulfuric acid and sodium hydroxide. Thus, these are written on the left side of the right arrow. The sodium sulfate and water have been the products and written on the right side of the right arrow.

The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:

Sodium hydroxide + Sulfuric acid →  Sodium sulfate +water

Where does acid rain occur?
vlabodo [156]
<span>Acid rain is precipitation that contains high levels of nitric or sulfuric acid. Natural and industrial sources can release sulfur dioxide and nitrogen oxide into the atmosphere, leading them to combine chemically with oxygen and water to form their respective acidic molecules. These acids are then deposited through rain or dust depending on the climate of the region. While acid rain can occur anywhere in the world, it is prevalent in regions that have high industrial activity.</span>
