Question

35. Answer the following questions :
(1) Explain the reaction of zinc grannules with an
le reaction of zinc grannules with dilute H, SO4 with chemical equation
zinc evolve H2 gas when it reacts with dilute HCl and dilute HNO3? Express
eaction with the equation of sine does not reacts with some
then give its reason.​

Answer 1

as we know that zinc is metal and (H2SO4 ,dilHCL,dilHNO3)are acid so when metal react with acid than salt and hydrogen gas produced...

Explanation:

here

when zinc react with H2SO4 than

Zn +H2SO4= ZnSo4 +h2

when zinc react with dil.HCL Than Zn + Hcl = zncl2 + h2

when zinc react with dil.HNO3 THAN zn + HNo3 = zn(NO3)2 +h2

but normally when metal react with HNO3 Than hydrogen gas not because HNO3 IS high oxidiging agent..sowhen zinc react with HNO3 there HNO3 should be dilute than salt and hydrogen gas produced...
