1.	When zinc metal is treated with a dilute solution of a strong acid, a gas is evolved, which is utilised in the hydrogenation of oil. Name the gas evolved. Write the chemical equation of the reaction involved and also write a test to detect the gas formed.
Answer» SOLUTION :When zinc reacts with dilute solution of strong acid, it forms salt and hydrogen gas is evolved. `Zn + 2HCl RARR ZnCl_(2) + H_(2)` When a burning splinter is brougth near the MOUTH of the test tube, the gas BURNS with a pop sound.
