Question

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type.

___H3PO4 + ___NaBr ⟶ ___HBr + ___Na3PO4

Answer 1

Double displacement reaction

Step-by-step explanation:

Chemical equation:

H₃PO₄ + NaBr → HBr + Na₃PO₄

Balanced chemical equation:

H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄

Step one:

H₃PO₄ + NaBr → HBr + Na₃PO₄

On left side of equation On right side pf equation

H = 3 H = 1

P = 1 P = 1

O = 4 O = 4

Na = 1 Na = 3

Br = 1 Br = 1

Step 2:

H₃PO₄ + NaBr → 3HBr + Na₃PO₄

On left side of equation On right side pf equation

H = 3 H = 3

P = 1 P = 1

O = 4 O = 4

Na = 1 Na = 3

Br = 1 Br = 3

Step 3:

H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄

On left side of equation On right side pf equation

H = 3 H = 3

P = 1 P = 1

O = 4 O = 4

Na = 3 Na = 3

Br = 3 Br = 3

Type of chemical reaction:

The given reaction is double displacement reaction on which cation and anion of both reactants are replace with each other.
