is the weakest intermolecular force. It is a temporary force that happens when
electrons of two adjacent atoms occupy positions that make atoms form dipoles
which are temporary dipoles. This is also referred as dipole-dipole attraction.</span>
When sodium phosphate reacts with sulfuric acid, forming sodium sulfate and phosphoric acid, the stoichiometric coefficient for sulfuric acid in the balanced chemical equation is 3.
In every balanced chemical equation, the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side. The stoichiometric coefficient is the number written in front of each reactants and products that tells how many moles of each are needed in the reaction.
The chemical equation for the given reaction is:
+
=
+ 
Put the necessary stoichiometric coefficient to balance each element.
Balancing Na:
+
=
+ 
Balancing P:
+
=
+ 
Balancing S:
+
=
+ 
Notice that H and O are already balanced.
Hence, the balanced chemical equation for the reaction is:
+
=
+ 
where 3 is the stoichiometric coefficient of sulfuric acid,
.
