Given the equation, the reaction is a double displacement reaction. The balanced equation is:
3NaBr + H₃PO₄ → Na₃PO₄ + 3HBr
What is a double displacement reaction?
This is a reaction in which there is an exchange of ions between reactants to produce a different product. The equation below illustrate a double displacement reaction:
AB + CD —> AD + CB
What is a chemical equation?
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Considering the equation
NaBr + __ H₃PO₄ → ___ Na₃PO₄ + __ HBr
The balanced equation is given as
3NaBr + H₃PO₄ → Na₃PO₄ + 3HBr
