Homework Equations

The Attempt at a Solution

Here is my answer:
Mg(OH)2,MgO,MgCO3,Mg(HCO3)2
Here is the model answer:
Mg,Mg(OH)2,MgO,MgCO3

Mg(HCO3)2 react with H2SO4 to give MgSO4:
Mg(HCO3)2 (aq) + H2SO4 (aq) --> MgSO4 (aq) + CO2(g) + H2O(l)

Is it possible for me to write Mg(HCO3)2?If not,please explain briefly.
THX a lot.

Can you show me a bottle of your magnesium bicarbonate? I was under the impression it was fairly unstable.

Apparenbtly it is stable enough to be offered for sale, google for its CAS number 2090-64-4.
