1.	If 40g of CaCO_3 is treated with 40g of HCl, which of the reactants will acts as limiting reagent?
Answer» `CaCO_3` HCl Both (a) and (b) None of these Solution :`underset("1 mole" (100g))(CaCO_3)+underset("2 moles" (73g))(2HCL) to CaCl_2+H_2O+CO_2` 100g of `CaCO_3` reacts with 73g of HCl 40g of `CaCO_3 " will reacts with " 73/100xx40=29.2g` of HCl SINCE `CaCO_3` iscompletely consumed and some AMOUNT (40-29.2=10.8g) ofHCl remains unreacted and hence, `CaCO_3` is limiting reagent.
