Finding Oxidation States

The oxidation states of the elements in the given compounds are as follows:

1. CO (Carbon Monoxide): - The oxidation state of oxygen is typically -2, and the oxidation state of carbon in CO can be calculated using the formula: - 2x + (-2) = 0, where x is the oxidation state of carbon. - Solving for x, we get x = +2 for carbon in CO.

2. CO2 (Carbon Dioxide): - The oxidation state of oxygen is typically -2, and the oxidation state of carbon in CO2 can be calculated using the formula: - 2x + 2(-2) = 0, where x is the oxidation state of carbon. - Solving for x, we get x = +4 for carbon in CO2.

3. H2CO3 (Carbonic Acid): - The oxidation state of oxygen is typically -2, and the oxidation state of hydrogen is +1. Using these values, we can calculate the oxidation state of carbon in H2CO3: - 2x + 3(-2) + 2(1) = 0, where x is the oxidation state of carbon. - Solving for x, we get x = +4 for carbon in H2CO3.

4. NaOH (Sodium Hydroxide): - The oxidation state of oxygen is typically -2, and the oxidation state of sodium is +1. Using these values, we can calculate the oxidation state of hydrogen in NaOH: - x + (-2) + 1 = 0, where x is the oxidation state of hydrogen. - Solving for x, we get x = -1 for hydrogen in NaOH.

5. Na2CO3 (Sodium Carbonate): - The oxidation state of oxygen is typically -2, and the oxidation state of sodium is +1. Using these values, we can calculate the oxidation state of carbon in Na2CO3: - 2x + 3(-2) + 2(1) = 0, where x is the oxidation state of carbon. - Solving for x, we get x = +4 for carbon in Na2CO3.

These oxidation states are based on the typical rules for assigning oxidation states to elements in compounds.
