Redox reactions and reducing agents?

Question

Balance the following redox reaction: KClO3 ® KCl + O2

What are the oxidation numbers for FeCl3?

Identify the reducing agent in this equation: C (s) + O2 (g) ® CO2 (g).

Identify the redox reaction.

1. MgCO3 ® MgO + CO2

2. Zn + CuSO4 ® ZnSO4 + Cu

3. NaCl + AgNO3 ® AgCl + NaNO3

4. none of the above

Which atom would be the strongest reducing agent.

1. K

2. Ca

3. Br

4. Kr

Which atom would be the strongest oxidizing agent?

Li

Be

N

F

I'm stumped on these questions, could anyone explain them to me?

any help would be greatly appreciated.

Answer 1

Balance the following redox reaction: 2KClO3  -->   2KCl + 3O2

What are the oxidation numbers for Fe+3    & Cl-1

Identify the reducing agent in this equation: C (s)  (gets oxidized)

Identify the redox reaction.

2. Zn + CuSO4 ® ZnSO4 + Cu
