Answer 2

Finding the Oxidation State of Ag2O, CaSO4, Al4C3, and Au2O3

To find the oxidation state of each compound, we can look at the oxidation numbers of the individual elements in the compound. The oxidation state is a measure of the degree of oxidation of an atom in a compound.

1. Ag2O (Silver Oxide): - The oxidation state of oxygen is typically -2. - Let the oxidation state of silver be x. - Since the compound is neutral, the sum of the oxidation states must be zero. - Therefore, we can set up the equation: 2x + (-2) = 0. - Solving for x, we find that the oxidation state of silver in Ag2O is +1.

2. CaSO4 (Calcium Sulfate): - The oxidation state of oxygen is typically -2. - The oxidation state of calcium is typically +2. - Let the oxidation state of sulfur be y. - Since the compound is neutral, the sum of the oxidation states must be zero. - Therefore, we can set up the equation: 2(+2) + y + 4(-2) = 0. - Solving for y, we find that the oxidation state of sulfur in CaSO4 is +6.

3. Al4C3 (Aluminum Carbide): - The oxidation state of carbon is typically -4. - Let the oxidation state of aluminum be z. - Since the compound is neutral, the sum of the oxidation states must be zero. - Therefore, we can set up the equation: 4z + 3(-4) = 0. - Solving for z, we find that the oxidation state of aluminum in Al4C3 is +3.

4. Au2O3 (Gold(III) Oxide): - The oxidation state of oxygen is typically -2. - Let the oxidation state of gold be w. - Since the compound is neutral, the sum of the oxidation states must be zero. - Therefore, we can set up the equation: 2w + 3(-2) = 0. - Solving for w, we find that the oxidation state of gold in Au2O3 is +3.

To summarize: - The oxidation state of silver in Ag2O is +1. - The oxidation state of sulfur in CaSO4 is +6. - The oxidation state of aluminum in Al4C3 is +3. - The oxidation state of gold in Au2O3 is +3.
