Respuesta :
For the given chemical equation, balanced equation with proper coefficients is 2Na₂HPO₄ → Na₄P₂O₇ + H₂O.
What are balanced chemical equations?
Balanced chemical equations are those equations in which each element of reactants and products are present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
Na₂HPO₄ → Na₄P₂O₇ + H₂O
In the above reaction all elements are not present in same quantity on either side, so we can balance the equation by multiply with coefficient 2 on the reactant side as below:
2Na₂HPO₄ → Na₄P₂O₇ + H₂O
Now the above reaction is balanced as all elements are present in qual amount.
Hence we will use coefficient 2 on the reactant side only.
