Oxidation States of Elements

To determine the oxidation states of the elements in the given compounds, let's analyze each compound individually:

1. CO (Carbon Monoxide): - Carbon (C) is more electronegative than oxygen (O), so it will have a negative oxidation state. - Oxygen (O) usually has an oxidation state of -2, except in peroxides where it has an oxidation state of -1. - Since CO is a neutral compound, the sum of the oxidation states must be zero. - Therefore, the oxidation state of carbon (C) in CO is +2, and the oxidation state of oxygen (O) is -2.

2. N2O5 (Dinitrogen Pentoxide): - Nitrogen (N) usually has an oxidation state of -3, except in compounds with more electronegative elements. - Oxygen (O) usually has an oxidation state of -2, except in peroxides where it has an oxidation state of -1. - Since N2O5 is a neutral compound, the sum of the oxidation states must be zero. - Therefore, the oxidation state of nitrogen (N) in N2O5 is +5, and the oxidation state of oxygen (O) is -2.

3. SO2 (Sulfur Dioxide): - Oxygen (O) usually has an oxidation state of -2, except in peroxides where it has an oxidation state of -1. - Since SO2 is a neutral compound, the sum of the oxidation states must be zero. - Let's assume the oxidation state of sulfur (S) is x. - The equation for the sum of the oxidation states is: x + 2(-2) = 0. - Solving the equation, we find that the oxidation state of sulfur (S) in SO2 is +4.

4. SO3 (Sulfur Trioxide): - Oxygen (O) usually has an oxidation state of -2, except in peroxides where it has an oxidation state of -1. - Since SO3 is a neutral compound, the sum of the oxidation states must be zero. - Let's assume the oxidation state of sulfur (S) is x. - The equation for the sum of the oxidation states is: x + 3(-2) = 0. - Solving the equation, we find that the oxidation state of sulfur (S) in SO3 is +6.

To summarize: - The oxidation state of carbon (C) in CO is +2, and the oxidation state of oxygen (O) is -2. - The oxidation state of nitrogen (N) in N2O5 is +5, and the oxidation state of oxygen (O) is -2. - The oxidation state of sulfur (S) in SO2 is +4, and the oxidation state of oxygen (O) is -2. - The oxidation state of sulfur (S) in SO3 is +6, and the oxidation state of oxygen (O) is -2.
