The equation 2NaNO3 CaCl2=2NaCl Ca(NO3)2 is balanced. How many atoms of oxygen are there on each side of the equations?

Respuesta :

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].
