The thermal decomposition of magnesium carbonate forms magnesium oxide and carbon dioxide.
MgCO3(s)→MgO(s)+CO2(g) \text{MgCO}_3(\text{s}) \rightarrow \text{MgO}(\text{s}) + \text{CO}_2(\text{g}) MgCO3(s)→MgO(s)+CO2(g)18.5 g of pure magnesium carbonate is decomposed completely. Calculate the mass of solid produced.
(Relative atomic masses: Mg=24.0\text{Mg} = 24.0Mg=24.0; C=12.0\text{C} = 12.0C=12.0; O=16.0\text{O} = 16.0O=16.0)
