MgCl2 because although K has a higher mass than Mg, the Mg compound with Cl has two atoms of Cl not one.
MgCl2 contain 25,537 % magnesium and 74,463 % chlorine. The atomic ratio is 2, the mass ratio is approx. 3.
Mg + MgCl2
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.
Balanced: MgO(s) + 2HCl(l) -> MgCl2(s) + H2O(l) Hope your still interested.....
The molar mass of magnesium chloride is 95,205 g.
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
HCl + Mg -----> MgCl2 + H2
2 HCl + Mg(OH)2 ----> MgCl2 + 2H2O
There are 1 Mg and 2 Cl.
The balanced equation is as follows: Mg + 2HCl --> MgCl2 + H2
