What volume of carbon (IV) oxide in dm 3 is produced at s.t.p. when 2.50g of CaCO3 reacts with excess acid according to the following equation? CaCO3(s) + 2HCI(aq) → CaCl2(aq) + H2O(1) + CO2(g)
[CaCO2 100; molar volume of a gas at s.t.p. = 22.4dm 3]
[CaCO2 100; molar volume of a gas at s.t.p. = 22.4dm 3]
