Indicate whether each of the following chemical conversions requires an oxidizing agent (o), a reducing agent (r), or neither (n). a) no31- nh3 b) po33- po43- c) agcl ag1+ + cl1- list the letter of your answers in order and separated by commas. for example, o, r,n

The answer is: R, O, N

Explanation:

Oxidizing agent is a chemical species that carries out the oxidation of another chemical species and gets reduced itself .

Whereas, reducing agent is a chemical species that carries out the reduction of another chemical species and gets oxidized itself .

a)  NO₃⁻ → NH₃

In the nitrate ion ( NO₃⁻), the oxidation state of the nitrogen (N) atom is +5.

Whereas, the oxidation state of the nitrogen (N) atom in ammonia (NH₃) is -3.

Thus in this reaction, nitrogen atom is getting reduced from +5 to -3 oxidation state.

Therefore, it requires a reducing agent (R).

b) PO₃³⁻ → PO₄³⁻

In the phosphite ion ( PO₃³⁻), the oxidation state of the phosphorus (P) atom is +3.

Whereas, the oxidation state of the phosphorus (P) atom in phosphate ion (PO₄³⁻) is +5.

Thus in this reaction, phosphorus atom is getting oxidized from +3 to +5 oxidation state.

Therefore, it requires an oxidizing agent (O).

c)  AgCl → Ag⁺ + Cl⁻

The oxidation state of silver (Ag) atom and chlorine (Cl) atom is +1 and -1, respectively.

In this reaction, the oxidation states of silver (Ag) atom and chlorine (Cl) atom remains unchanged.

Therefore, it does not require a oxidizing agent or a reducing agent (N).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

the answer is d.) potassium
