Oxidation States and Compounds

The oxidation state, also known as the oxidation number, of an element in a compound indicates the number of electrons that the element has gained or lost. Here are the answers to your questions:

1. Compounds with an oxidation state of +4: - Carbon dioxide (CO2) has a carbon atom with an oxidation state of +4 [[1]]. - Potassium oxide (K2O) has a potassium atom with an oxidation state of +1 and an oxygen atom with an oxidation state of -2. The average oxidation state of potassium is +1, and the average oxidation state of oxygen is -2, resulting in an overall oxidation state of +4 for the compound [[2]]. - Hydrogen fluoride (HF) has a hydrogen atom with an oxidation state of +1 and a fluorine atom with an oxidation state of -1. The average oxidation state of hydrogen is +1, and the average oxidation state of fluorine is -1, resulting in an overall oxidation state of +4 for the compound [[3]].

2. Compound with an oxidation state of 0: - Iron sulfide (FeS) has an iron atom with an oxidation state of 0 [[4]].

3. Oxidation state of chlorine in compounds with an oxidation state of +7: - Potassium chlorate (KCLO3) has a chlorine atom with an oxidation state of +7 [[5]]. - Perchloric acid (HCLO4) has a chlorine atom with an oxidation state of +7 [[6]]. - Chlorine gas (Cl2) has chlorine atoms with an oxidation state of 0 [[7]].

4. Lowest oxidation state of sulfur: - The lowest oxidation state of sulfur is -2 [[8]].
