Write a balanced equation for the reaction of sulfuric acid (H,SO) and
Sonbull [250]

Answer:

Explanation:

Word equation:

sulfuric acid + ammonium hydroxide  →  ammonium sulfate + water

Chemical equation:

H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O

Balanced chemical equation:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O

The given reaction is the reaction of acid with base. When acid and base react salt and water are produced. In given reaction an acid sulfuric acid and base ammonium hydroxide react and form ammonium sulfate salt and water. The given reaction also follow the law of conservation of mass.

Steps to balance the equation:

Steps 1;

H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O

H = 7                            H = 10

S = 1                             S = 1

O = 5                           O = 5

N = 1                            N = 2

Step 2:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + H₂O

H = 12                            H = 10

S = 1                             S = 1

O = 6                           O = 5

N = 2                           N = 2

Step 3:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O

H = 12                            H = 12

S = 1                               S = 1

O = 6                             O = 6

N = 2                             N = 2
