Dear student,

Iron does not react with water in the ordinary temperature. It reacts only with steam. When steam is passed over red-hot iron, iron (II,III) oxide and hydrogen gas are formed.

As, we know that Mg is a metal and when it reacts with dilute acid it forms salt and hydrogen gas. Mg + H 2 SO 4 (dil) forms MgSO 4 + H 2

abhishek · Answer

we all know magnesium is a metal when it react with react with dilute acid say H2SO4 , the cation magnesium get react with sulphur dioxide present in H2S04 because H2S04 is anion and form MGS04 and hydrogen is also formed

Dear Student

1. Iron does not react with water in the ordinary temperature. It reacts only with steam. When steam is passed over red-hot iron, iron (II,III) oxide and hydrogen gas are formed.

2. Magnesium is more reactive than hydrogen and it displaces hydrogen from dilute acids. Magnesium reacts with dilute sulphuric acid to form magnesium sulphate and hydrogen gas is evolved. This is a single displacement reaction and also exothermic.

3.When steam is passed over red hot coke, water gas (CO+ H₂O)is formed.

I hope this answer will help you.
Thanks & Regards
