MgCl2
The chemical equation SiCl + Mg → MgCl2 + Si is not balanced. To balance it, you would need to adjust the coefficients to ensure that the number of atoms of each element is the same on both sides of the equation.
MgCl2 plus 2H20 produces Mg(OH)2 plus 2HCl
The chemical equation is:MgF2 + 2 Na = 2 NaF
The reaction is:MgO + H2O = Mg(OH)2

MgCl2 plus 2H20 produces Mg(OH)2 plus 2HCl
Balanced Equation: 2Mg(NO3)2 = 2MgO + 4NO2 + O2
MgO2
The chemical equation is:MgF2 + 2 Na = 2 NaF
The balanced equation for Mg + O2 is 2Mg + O2 → 2MgO.
The reaction is:MgO + H2O = Mg(OH)2
So you have 3 Cl on the left and 2cl on the right. First off you put a 2 in front of the AlCl3 to give you 6 Cl, and you put a 3 in front of the MgCl2 to also give you 6Cl on the right side. You then have to balance the Mg and Al, so put a 3 in front of the Mg on the left to give you 3Mg, and 2 in front of the Al on the right to give you 2Al. Your final, balanced formula is 3Mg + 2AlCl3 => 3MgCl2 + 2Al
