In each of the following balanced oxidation-reduction equations, identify those elements that undergo changes in oxidation number and indicate the magnitude of the change in each case.

Part A

I2O5(s)+5CO(g)→I2(s)+5CO2(g)

What are the elements changing the oxideation number?

Enter your answers as chemical symbols separated by a comma.

Indicate the magnitude of the change in this case.

Part B

2Hg2+(aq)+N2H4(aq)→2Hg(l)+N2(g)+4H+(aq)

What are the elements changing the oxideation number?

Enter your answers as chemical symbols separated by a comma.

Indicate the magnitude of the change in this case.

Part C

3H2S(aq)+2H+(aq)+2NO−3(aq)→3S(s)+2NO(g)+4H2O(l)

What are the elements changing the oxideation number?

Enter your answers as chemical symbols separated by a comma.

Indicate the magnitude of the change in this case.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
