Question

Oxygen gas reacts with hydrogen to produce water. The reaction is represented by the equation:
$O_2\left(g\right)+H_2\left(g\right)⟶H_{2}O\left(g\right)$
The above reaction is an example of
a) Oxidation of hydrogen
b) Reduction of oxygen
c) Reduction of hydrogen
d) Redox reaction

• A. (a), (b) and (c)
• B. (b), (c) and (d)
• C. (a), (c) and (d)
• D. (a), (b) and (d)

Answer 1

Answer: (D)

(a), (b) and (d)

As in the given equation , the electrons are transferred from Hydrogen to Oxygen , hence Oxygen is reduced and electrons are accepted by Oxygen from Hydrogen , hence Hydrogen is oxidised . Now , both oxidation and reduction are going together , therefore it is a Redox (Reduction- Oxidation reaction) reaction . The opions (a) ,( b) and (d) are correct .
