`100 g CaCO_(3)` reacts with `1 litre 1 N HCl`. On completion of reaction how much weight of `CO_(2)` will be obtain

If 20 g of CaCO_(3) is treated with 100 mL of 20% HCl solution, the amount of CO_(2) produced is

The volume of CO_(2) at STP obtained by heating 1 g of CaCO_(3) will be

The volume of CO_(2) at STP obtained by heating 1 g of CaCO_(3) will be

2.1 g of a mixture of NaHCO_3 and KCIO_3 required 100 " mL of " 0.1 HCl for complete reaction. Calculate the amount of residue that would be obtained on heating 2.2 g of the same mixture strongly.
