Calcium carbonate, CaCO3, decomposes upon heating according to the following equation.
CaCO3 (s) ∆ CaO (s) + CO2 (g)
0.20 mol of CaCO3 is heated in a 2.0 L vessel. After heating, it is found that the pressure of
the gas is 44.08 kPa at 30°C.
i) Determine the number of moles of gas formed from the decomposition of CaCO3 .
ii) The mass of CaCO3 left after the reaction was completed
iii) The partial pressure of hydrogen gas in the vessel when 0.10 mol of hydrogen gas is added
to the vessel at the same temperature.
