MgCl2, MgCO3, and Mg(NO3)2 are all different chemical compounds with different formulas and properties.
MgCl2 is magnesium chloride, MgCO3 is magnesium carbonate, and Mg(NO3)2 is magnesium nitrate. These compounds have different chemical structures and compositions, so they are not equal to each other.
