Balance Mg(OH)2 + HNO3 = H2O + Mg(NO3)2 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element...
2Na+(aq) + 2OH-(aq) + Mg2+(aq) + 2NO3-(aq) = Mg(OH)2(s) + 2Na+(aq) + 2NO3-(aq) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. Na+ NO3- ...
