Question

Which of the following metals can displace hydrogen from hydrochloric acid solution? Write appropriate equations for any reactions that can occur Al, Cu, Ag Also write a short note on active metals which can displace hydrogen from water. plz ans . it fast

Answer 1

Answer:

Hydrogen can be displaced by metals that lie above hydrogen in activity series of metals

only Al can displace hydrogen from HCl from given options

2AL + 6HCl = 2AlCl3 + 3H2

Answer 2

Answer:

Hydrogen can be displaced by metals that lie above hydrogen in activity series of metals

only Al can displace hydrogen from HCl from given options

2AL + 6HCl = 2AlCl3 + 3H2
