Login2 ml of NaOH solution is added to a few pieces of granulated zinc metal taken in a test tube. When the contents are warmed, a gas evolves which is bubbled through a soap solution before testing.
(i) Write the equation of the chemical reaction involved and the test to detect the gas.
(ii) Name the gas which will be evolved when the same metal reacts with dilute solution of a strong acid.

The gas can be detected by bringing a burning SPLINTER near the mouth of the TEST TUBE. If the gas burns with a BLUE flame and produces a pop sound. The gas evolved is Hydrogen.
(II) `Zn+HCl("dil") rarr ZnCl_(2) + H_(2)`
`H_(2)` gas is evolved in this reaction too.
