3. The reaction of solid magnesium carbonate (MgCO3) with aqueous hydrochloric acid (HCl) is given below:
MgCO3(5) + 2 HCl(ag) → MgCl(ag)+H2OM + CO2@)
AH°rn=-34.5 kJ
If 1.3443 g of solid magnesium carbonate (M = 84.32 g/mol) are reacted with
54.90 mL of 0.656 M hydrochloric acid (M = 36.46 g/mol),
a) Determine which of the two reactants (MGCO3) or HCla9) is the limiting reagent.
b) Determine how much heat (AH ~ kJ) will be produced when:
the 1.3443 g of solid magnesium carbonate MGCO3) reacts with
the 54.90 mL of 0.656 M hydrochloric acid. HClag)
