Question

What will happen when Iron will react with:

Oxygen
Water
Hydrochloric Acid
Sulphuric Acid ​

Answer 1

Hello Buddy

Oxygen

2Fe+O2 gives 2FeO (Iron oxide)

Water

Fe + H2O gives FeO + H2 (Iron oxide and hydrogen gas is evolved)

Hydrochloric Acid

Fe + 2HCl gives FeCl2 + H2 ( Iron Chloride and hydrogen gas is evolved)

Sulphuric Acid

Fe+H2SO4 gives FeSO4 + H2 ( Iron Sulphate and hydrogen gas is evolved)

Hope it helps
