Question

Read the following chemical equations. Reaction 1: CH4 + 2O2 → 2H2O + CO2 Reaction 2: 2CuO + C → 2Cu + CO2 Which of the following statements is true for both the chemical equations? Carbon is reduced in both the reactions. Carbon is oxidized in both the reactions. Carbon is reduced in reaction 1 and oxidized in reaction 2. Carbon is oxidized in reaction 1 and reduced in reaction 2.

Answer 1

B

Step-by-step explanation:

Carbon is oxidized in both the reactions.

Answer 2

The correct option is B) Carbon is oxidized in both the reactions.

Step-by-step explanation:

Oxidation can be described as the loss of electrons, ions or atoms. Reduction can be described as the gain of electrons, ions or atoms.

In reaction 1: CH4 + 2O2 → 2H2O + CO2

Carbon is losing hydrogen atoms to become carbon dioxide. Hence, we will say that carbon is being oxidized.

In reaction 2: 2CuO + C → 2Cu + CO2

In this reaction also, carbon is oxidized into carbon dioxide by losing electrons.

Hence, in both the reactions, carbon is being oxidized.
