2MgO ==> 2Mg + O2
For Zn (CO3) =>> Zn + CO3 or would it be ZnO + CO2 how would you determine this?
Carbonates, when heated, usually decompose to CO2 and the metal oxide so
ZnCO3 ==> ZnO + CO2. Also you know there is a CO and a CO2 but no CO3 (although the [CO3]^2-) exists--as in ZnCO3, Na2CO3, etc).
ZnCO3 ==> ZnO + CO2. Also you know there is a CO and a CO2 but no CO3 (although the [CO3]^2-) exists--as in ZnCO3, Na2CO3, etc).
