2 upper H subscript 3 upper P upper O subscript 4 (a q) plus 3 upper C a (upper O upper H) subscript 2 (a q) right arrow upper C a subscript 3 (upper PO upper O) subscript 4 (s) plus 6 upper H subscript 2 upper O (l).

Answer 1

Answer:

H₂SO₄(aq) + NaOH(aq)   → Na₂SO₄(aq) +  H₂O(I)

Explanation:

Chemical equation:

H₂SO₄(aq) + NaOH(aq)   → Na₂SO₄(aq) +  H₂O(I)

Balanced chemical equation:

H₂SO₄(aq) + 2NaOH(aq)   → Na₂SO₄(aq) +  2H₂O(I)

It is an acid base reaction. Sulfuric acid and sodium hydroxide react to form the salt and water.

The reaction follow the law of conservation of mass because there are equal number of atoms on both side of equation.

According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Type of reaction:

It is double displacement reaction.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Answer 2

The formula equation for the reaction between sulfuric acid and dissolved sodium hydroxide is

Upper H subscript 2 upper S upper O subscript 4 (aq) plus 2 upper Na upper O upper H (aq) right arrow upper Na subscript 2 upper S upper O subscript 4 (aq) plus 2 upper H subscript 2 upper O (l).

Determination of the equation

Sulphuric acid => H₂SO₄

Sodium hydroxide => NaOH

The reaction between sulfuric acid, H₂SO₄ and sodium hydroxide, NaOH is a neutralization reaction in which salt and water is formed. This is given below:

H₂SO₄(aq) + NaOH(aq) → Na₂SO₄(aq) +  H₂O(I)

The equation can be balance as follow:

There are 2 atoms of Na on the right side and 1 atom on the left side. It can be balance by writing 2 before NaOH as shown below:

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) +  H₂O(I)

There are a total of 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) +  2H₂O(I)

Now, the equation is balanced.

Thus, the correct answer to the question is:

Upper H subscript 2 upper S upper O subscript 4 (aq) plus 2 upper Na upper O upper H (aq) right arrow upper Na subscript 2 upper S upper O subscript 4 (aq) plus 2 upper H subscript 2 upper O (l).
