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 and also write a test to detect the gas formed.
Answer» SOLUTION :When zinc reacts with DILUTE solution of strong solution of strong acid, it forms salt and hydrogen gas is evolved. `Zn + 2HCl rarr ZnCl_(2)+H_(2)` When a BURNING splinter is BROUGHT near the mouth of the TUBE , the gas burns with a pop sound.
