Question

write the reaction of iron with water and explain various steps of it to balance it
​

Answer 1

Explanation:

Chemical equations are symbolic descriptions of chemical reactions wherein the reactants and the products are represented in terms of their respective chemical equations. They often include the use of symbols to represent variables including the path of the reaction and the physical responses of the reacting entities.

(1) The chemical equation for the reaction of iron with steam can be written as

3Fe(s) + 4H2O → Fe3O4 + H2

Iron + Water → Iron (II, III) oxide + hydrogen gas

The formation of iron(II, III) oxide and hydrogen when red hot iron interacts with steam.

When an iron metal interacts with steam, metal oxide and hydrogen gas are the products that are produced.

(2) The chemical equation for the reaction of calcium with water can be written as

When a metal interacts with water, metal hydroxide and hydrogen gas are the products that are produced.

Metal + steam → Metal hydroxide + Hydrogen

Calcium reacts with cold water to form calcium hydroxide and hydrogen gas.

Ca(s)+ 2H2O(l) → Ca(OH)2(aq) + H2(g)

(3) The chemical equation for the reaction of potassium with water can be written as

To produce potassium hydroxide and hydrogen gas, potassium reacts violently with cold water.

During the process, much heat is generated that the hydrogen gas generated caught on fire and rapidly burns.

2K(s)+ 2H2O(l) → 2KOH(aq) + H2(g) + heat.

The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Boiling the water removes the oxygen and the layer of oil prevents it from re-entering.
