We have to balance the given chemical equation and determine the type of chemical reaction taking place.
A balanced chemical equation is an equation which has an equal number of atoms of each element on both sides.
Let’s start by counting all the atoms on both sides of the equation.
NaBr + H3PO4 → Na3PO4 + HBr
Na = 1 Na = 3
Br = 1 Br = 1
H = 3 H = 1
P = 1 P = 1
O = 4 O = 4
Balance the following equation and indicate the type of reaction taking place:
___ NaBr + ___ H3PO4 → ___ Na3PO4 + ___ HBr
