Answer» Correct Answer - D `{:("Mg" " " + " " 2HCl " " to MgCl_(2) + H_(2)), (2.4 g """""" " (1M, 100"ml")" ), (0.1 "mol" " " 0.1 "mol"), (underline(-0.05)), (0.05 "mol"):}` HCl is a limiting reagent `0.1` mol HCl give `(0.1)/(2)` mol `H_(2)` or `1.12` lit `H_(2)` at STP `0.05` mol Mg left `therefore` None of these is wrong. |
