Question

What do you obserw on the surface of zinc granules ​

Answer 1

HERE IS YOUR ANSWER .... IN DETAILS......

_______________________________

When we treat zinc granules with sulfuric acid, we notice bubbles (of hydrogen gas) forming on the surface. We also note some zinc sulfate dihydrate forming:

When we treat zinc granules with sulfuric acid, we notice bubbles (of hydrogen gas) forming on the surface. We also note some zinc sulfate dihydrate forming:Zinc + sulfuric acid + water (dilute acid) = zinc sulfate dihydrate + hydrogen

When we treat zinc granules with sulfuric acid, we notice bubbles (of hydrogen gas) forming on the surface. We also note some zinc sulfate dihydrate forming:Zinc + sulfuric acid + water (dilute acid) = zinc sulfate dihydrate + hydrogenZn + H2SO4 + 2H2O(l) = ZnSO4•2H2O + H2(g)

We also note some zinc sulfate dihydrate forming:Zinc + sulfuric acid + water (dilute acid) = zinc sulfate dihydrate + hydrogenZn + H2SO4 + 2H2O(l) = ZnSO4•2H2O + H2(g)Change in Free Energy: ΔG(20C) = -205.9kJ (negative, so the reaction runs)
