2 mL of sodium  hydroxide  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. Write the equation  of the chemical reaction involved  and the test to  detect  the gas. Name the  gas which will be evolved  when the same metal  reacts  with dilulte   solution  of strong acid.
