Answer 1

Answer:

hope it helps u dear

plz mark as brainlist answer

Explanation:

There are two potential reactions that can take place - with dilute H2SO4, you get a standard metal-acid redox reaction - Iron (II) Sulphate & hydrogen gas are the products:

Fe (s) + H2SO4 (aq) → FeSO4 (aq) + H2 (g)

In hot concentrated solutions, the acid acts as an oxidising agent, the redox reaction producing iron (III) sulphate, water and sulphur dioxide gas

2Fe (s) + 6H2SO4 (l) → Fe2(SO4)3 (aq) + 3SO2 (g) + 6H2O (l)
