plz ans fasttttttttttttt

Answer 1

Answer:

d. is the right answer. i think this is first chapter of 10th ncert. first chapter excercise question. thanx for remembering me i studyed it last year

Answer 2

Answer:

There is oxidation H₂ and reduction of 3Fe i.e.option(a).

Explanation:

The reaction proceeds as follows:-

$\mathrm{Fe_3O_4+4H_2O\longrightarrow 3Fe+4H_2O}$         (1)

Where,

Fe₃O₄=Iron(II, III)oxide

H₂=Hydrogen

H₂O=Water

Fe=Iron

Let's understand what is oxidation and reduction first.

• Oxidation-The removal of hydrogen or any other electropositive element, or the addition of oxygen, is said to be the process of oxidation in classical or earlier concepts. The process of an atom or ion losing one or more electrons is known as oxidation, according to the electronic notion.
• Reduction-Reduction is a process that involves the addition of hydrogen or any other electropositive element or the removal of oxygen or any other electronegative element, according to classical or older concepts. The process through which an atom or an ion gains one or more electrons is known as reduction, according to the electronic idea.

So, from equation (1) we can see that there is the oxidation of hydrogen(H₂) and reduction of iron(Fe).

Hence, among the given options the correct answer is (a) i.e. Oxidation H₂, Reduction 3Fe.
