Consider the following reaction:
I2O5(s) + 5 CO (g) → I2(s) + 5 CO2(g)

Which of the following correctly characterizes this reaction?
The oxidation number of iodine in the reactants is +5.
CO is oxidized.
I2O5 is the oxidizing agent.

The three statements are true

Explanation:

For the reaction:

I₂O₅(s) + 5CO(g) → I₂(s) + 5CO₂(g)

State oxidation of iodine in I₂O₅ is:

5 O²⁻ = 10⁻

As you have 2 I and the molecule has no charge, oxidation state of I is +5.

The carbon in CO has an oxidation state of +2 and in CO₂ is +4. That means the carbon is oxidized

An oxidizing agent is a substance that produce the oxidation of the agent that reacts with this one. CO is oxidized because of I₂O₅ is producing its oxidation being the oxidizing agent

Thus, the three statements are true.

c is the answer because when something is left after something evaporates that shows the chemical change.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
