In the reaction of water, 2H2 is oxidized to form 2H2O by gaining oxygen atom which shows that 2H2 is reducing agent as it undergoes oxidation.
<h3>What is reducing agent?</h3>
A reducing agent is a type of chemical that "donates" an electron to another atom that needs an electron. This type of reaction in which loss of electron occurs is called reduction reaction.
So we can conclude that 2H2 is oxidized to form 2H2O by gaining oxygen atom which shows that 2H2 is reducing agent as it undergoes oxidation.

Answer: FeO is called ferrous oxide while Fe2O3 is ferric oxide
Explanation:
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 elections in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons to share. Ferric oxide, is commonly known as iron(III) oxide
The empirical formula : C₆H₂Cl₂O
The molecular formula : C₁₂H₄Cl₄O₂
<h3>Further explanation</h3>
Given
The percentage composition
Required
The empirical formula and the molecular formula
Solution
The mol ratio of the components :
C : H : Cl : O
=44.76/12 : 1.25/1 : 44.05/35.5 : 9.94/16
=3.73 : 1.25 : 1.241 : 0.621 divide by 1.241
= 3 : 1 : : 1 : 0.5 x 2
= 6 : 2 : 2 : 1
The empirical formula : C₆H₂Cl₂O
(Empirical formula)n=molecular formula
(C₆H₂Cl₂O)n=321.97
(160.986)n=321.97
n=2
(C₆H₂Cl₂O)₂=C₁₂H₄Cl₄O₂
The molecular formula : C₁₂H₄Cl₄O₂
