Question

(C) A 2 : 3 molar ratio mixture of Na2CO3 and MgCO3 produces 0.3 moles of CO2 per mole of the initial mixture upon strong heating.true or false

Answer 1

Answer:

Na2CO3 changes to Na2O and CO2 on strong heating whereas MgCO3 changes to MgO and CO2. 1 mole of CO2 is produced by each being 1 mole initially. The mixture is in the molar ratio of 2:3. So, for 1 mole of the mixture, it will have 0.4 moles of Na2CO3 and 0.6 moles of MgCO3. So they will produce 1 mole of CO2. So, your answer is not correct
