hi frnd here is ur ans,
Al react more quickly than zinc with HCL because it is the highly reactive metal than zinc.
...I hope this will help you pls mark as brainliest ☺

bishista:
Aluminium is more reactive than zinc
no
????,
Pls check the reactivity order. It goes as follows k,na,ca,al,zn,fe,pb,h,cu,hg,ag,au
ooooo yes
then ans ???
ss ur question may be wrong
i can send pic yaar

Hey Vipin here is ur answer .....
→ Zinc is more reactive than aluminium.
→ Secondly, aluminium oxide forms an insoluble residue on the surface of the metal
→ Thus preventing it from reacting with the acid.
→ These two reasons lead to the difference in the rates of the two reactions.
→ Also recall the reactivity series
→ The reaction between zinc and hydrochloric acid is -
Zn + HCl = H2 + ZnCl2.
→ It is a single replacement reaction wherezinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt.
→ Zinc reacts quickly with the acid to form bubbles of hydrogen.
→ Reaction of aluminium withacids. Aluminium metal dissolves readily in dilute sulphuric acid to form solutions containing the aquated Al(III) ion together with hydrogen gas, H2.
→ The corresponding reactions with dilute hydrochloric acid also give the aquated Al(III) ion.
