Question

when Metal X is treated with a dilute acid Y then a gas Z that is evolved which burns readily by making a little explosion a) name any two metals which can behave like metal X b) name any two assets which can behave like acid Y c) name the gas Z d) is the reaction between Metal X and Y exothermic and endothermic? e) write the balanced chemical equation for the reaction which takes place.​

Answer 1

Answer:

a) Two metals that can behave like metal X are Zinc and Iron.

b) Two acids which can behave like acid Y are dilute hydrochloric acid and dilute sulphuric acid

c) The gas Z is Hydrogen.

d) The reaction between metal X and dilute acid Y is exothermic.  

e) Suppose metal X is zinc (Zn) and acid Y is dilute hydrochloric acid (HCl) so,

Zn(s)+2HCl(aq)→ZnCl2 (aq)+H2(g)

please mark me the brainliest...
