Answer: There are 6 atoms on reactant side and 6 atoms on product side.
Explanation:
[tex]2NaNO_3 + CaCl_2 \rightarrow 2NaCl + Ca(NO_3)_2[/tex]
As can be seen from the balanced equation the no of atoms i 1 molecule of [tex]NaNO_3[/tex] is 3, thus 2 molecules contain 6 atoms.
According to law of conservation of mass, in a balanced chemical equation the number of atoms on product side must be equal to the number of atoms on reactant side.
Thus there are 6 atoms formed in [tex]Ca(NO_3)_2[/tex].
