When dilute HCl reacts with Zinc metal, the gas liberated is?
Oxygen
Nitrogen
Chlorine
Hydrogen
When dilute HCl reacts with Zinc metal, hydrogen gas is liberated.
Which gas is liberated when zinc reacts with dilute nitric acid?
Hydrogen gas is prepared in the laboratory by reacting dilute HCl with granulated zinc. Following reaction takes place
Zn+2HCl→ZnCl2+H2
Calculate the volume of hydrogen gas liberated at STP when 32.65 g of zinc reacts with HCl. 1 mol of a gas occupies 22.7 L volume at STP; atomic mass of Zn = 65.3u
