5 g of Zn reacts with (I) Excess of NaOH (II) Dilute HCl, then volume ratio of `H_2` gas evolved in (I) and (II) is

When the same amount of zinc is treated with excess if H_2SO_4 and with excess if NaOH, the ratio of the volumes of H_2 evolved , is

When same amount of zinc is treated separately with excess of H_(2)SO_(4) and NaOH , the ratio of volumes of H_(2) evolved is:

When same amount of zinc is treated separately with excess of H_(2)SO_(4) and NaOH , the ratio of volumes of H_(2) evolved is:

When the same amount of Zn is treated with excess of H_(2)SO_(4) and excess of NaOH separately, the ratio of the volume of hydrogen evolved is-

When the same amount of zinc is treated separately with excess of H_(2)SO_(4) and excess of NaOH , the ratio of volumes of H_(2) evolved is:

When the same amount of zinc is treated separately with excess of H_(2)SO_(4) and excess of NaOH, the ratio of volumes of H_(2) evolved is

5 g of zinc is treated separately with an excess of (a) dilute hydrochloric acid and (b) aqueous sodium hydroxide The ratio of the volumes of H_(2) evolved in these two reactions is
