Answer:
H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄
Double displacement reaction
Explanation:
Chemical equation:
H₃PO₄ + NaBr → HBr + Na₃PO₄
Balanced chemical equation:
H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄
Steps to balance:
H₃PO₄ + NaBr → HBr + Na₃PO₄
H = 3 H = 1
P = 1 P = 1
O = 4 O = 4
Na =1 Na = 3
Br = 1 Br = 1
We will add the coefficient 3 with NaBr.
H₃PO₄ + 3NaBr → HBr + Na₃PO₄
H = 3 H = 1
P = 1 P = 1
O = 4 O = 4
Na = 3 Na = 3
Br = 3 Br = 1
Now we will add the coefficient 3 with HBr.
H₃PO₄ + 3NaBr → 3HBr + Na₃PO₄
H = 3 H = 3
P = 1 P = 1
O = 4 O = 4
Na = 3 Na = 3
Br = 3 Br = 3
Now equation is completely balanced.
The reaction type 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
