Answer 1

1. $\large \tt2Zn + 2HCl → 2ZnCl + H_2$

Answer 2

Answer:

when zinc granules are added to HCL then as zinc is more reactive than hydrogen so it will displace hydrogen and take its place and form zinc chloride and H2 will be released.

and balanced equation for it

zn+ hcl_zncl2 +h2

zn+2hcl_ zncl2+ h2
