A quantity of electrical charge that brigns about the depositiion of `4.5g Al` from `Al^(3+)` at the cathode will also produce the following volume `(STP)` of `H_(2)(g)` from `H^(o+)` at the cathode.A. ` 11. 2 L`B. ` 44.8 L`C. ` 5.6 L`D. ` 22 .4 L` |
Answer» Correct Answer - C Eq. of `H_2 =` Eq . Of `Al = ( 4.5)/(27 .3) =0.5` `:. 1 eq .H_2 = 11 . 2 L` ` :. 0 5 eq . H_2 = 5. 6 L` . |
