A mixture contained calcium carbonate, CaCO3, and magnesium carbonate, MgCO3. A sample of this mixture weighing 7.85
Question:
CaCO3(g) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
MgCO3(s) + 2HCl(aq) → MgCl2(aq) + H2O(l) + CO2(g)
If the sample reacted completely and produced 1.94 L of carbon dioxide, CO2, at 25oC and 785 mmHg, what were the percentages of CaCO3 and MgCO3 in the mixture?
