The decomposition reaction of magnesium dichloride results in magnesium metal and chlorine gas. The reaction is MgCl2 -> Mg + Cl2.
MgCl2 + H2O --> Mg+2 + Cl-
CO2 and MgO
MgO + CO2
relative formula mass of MgCO3
The chemical formula* for magnesium carbonate is MgCO3. *Note that compounds have chemical formulas; elements have chemical symbols.
double replacement and decomposition
MgCO3 has 5 atoms One Mg One C Three O
With sufficient heating, MgCO3 -> MgO + CO2, magnesium oxide and carbon dioxide.
The decomposition reaction is:MgCO3 = MgO + CO2
Thermal decomposition. MgCO3(s) ==heat==> MgO + CO2
100 grams MgCO3 (1mol MgCO3/84.32g) = 1.19 moles of MgCO3
The ratio of MgCO3 to WHAT!

That's an easy one to balance as long as know the products. Magnesium carbonate decomposes into magnesium oxide and carbon dioxide. Here's the equation: MgCO3 --> MgO + CO2. The equation requires no coefficients to balance; it balances itself.
The chemical equation is:MgCl2 + Li2CO3 = MgCO3(s) + 2 LiCl
The reaction is:MgCO3 = MgO + CO2
