The reaction between sulfuric acid (H2SO4) and sodium hydroxide (NaOH) to form sodium sulfate (Na2SO4) and water can be written: NaOH + H2SO4 → H2O + Na2SO4. This is an incomplete equation, since the same number of atoms does not appear on both sides of the reaction (for example, 1 sodium atom appears in the reactants, but 2 sodium atoms appear in the products). Such a reaction could not actually occur. Correcting this fault is called balancing the equation. Placing a 2 in front of the NaOH balances the number of sodium atoms, as well as the hydrogen and oxygen atoms. The balanced equation is: 2NaOH(aq) + H2SO4 → 2H2O(l) + Na2SO4(aq); this equation implies that two molecules of NaOH are necessary to react with each molecule of H2SO4. An equation must be balanced before a chemist can make calculations based on it.

Calcium nitrate + Sodium carbonate = Calcium carbonate + Sodium nitrate.
There's 2 (NO3) molecules,so on the other side there should be 2 as well
There is also 2 Na molecules.So,the equation will be
Ca(No3)2 + Na2CO3 = CaCo3 + 2 NaNo3
