7. Magnesium carbonate, MgCO3, decomposes when heated in a similar reaction to calcium carbonate.
(-did other questions)
d) Magnesium carbonate also reacts with dilute hyrochloric acid:
MgCO3 + 2HCl ------ MgCl2 + H2O +CO2
(s) (aq) (aq) (l) (g)
i) 8.4g of magnesium carbonate was added to 25cmcubed dilute hydrochloric acid with a concentration of 0.20mol/dmcubed. Show which reactant is the limiting reactant.
ii) What volume of carbon dioxide gas was given off in the reaction described in part i, at room temperature?
(Please explain and it is quite urgent)

For part ii, find the number of moles CO2 created by the reaction and multiply that by 24dm3
