Identify the oxidizing agent and the reducing agent for the following reaction: Zn(s)+Cu2+(aq)→Zn2+(aq)+Cu(s) Express your answe

Ainat [17]

Answer: oxidizing agent: $Cu^{2+}$ , reducing agent : $Zn$

Explanation: Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

For the given reaction:

$Zn(s)+Cu^{2+}(aq)\rightarrow Zn^{2+}(aq)+Cu(s)$

On reactant side:

Oxidation state of zinc = 0

Oxidation state of copper = +2

On product side:

Oxidation state of zinc = +2

Oxidation state of copper = 0

The oxidation state of copper reduces from +2 to 0, it is getting reduced. The substance which itself gets reduced, oxidizes other and is called as oxidizing agent.Thus $Cu^{2+}$ acts as oxidizing agent.

The oxidation state of zinc increases from 0 to +2. Thus, it is getting oxidized and it undergoes oxidation reaction. The substance which itself gets oxidized, reduces other and is called as reducing agent.Thus $Zn$ acts as reducing agent.

What form the ideal gas law would you use to calculate the temperature of a gas

Charra [1.4K]

You can use any form of the Ideal Gas Law, but usually one form is more convenient, depending on the information given.

There are three forms of the Ideal Gas Law.

Form 1

P V = n R T

If the question gives you the number of moles then

, this is the most convenient one to use.

Form 2

P V = m M R T , where m is the mass of the gas and

M is its molar mass.

If the question gives you the mass

, this is the most convenient one to use.

Form 3

P = ρ M R T , where ρ is the density of the gas. If the question gives you the density

ρ , this is the most convenient one to use.
