Choose the correct statement. The cathode is the electrode where the oxidation takes place. Both oxidation and reduction may tak

e place at the cathode, depending on the cell. The cathode is always positive. The anode is always negative. The cathode is the electrode where the reduction takes place.

Answer:

The cathode is the electrode where the reduction takes place.

Explanation:

Cell has three components:

an electrolyte and two electrodes which is a cathode and an anode.

Electrolyte is usually solution of the water or other solvents in which the ions are dissolved.

<u>In electrolytic cell:</u>

Negatively charged electrode is the cathode where the process of reduction takes place.

Positively charged electrode is the anode where the process of oxidation takes place.

<u>In galvanic cell:</u>

Positively charged electrode is the cathode where the process of reduction takes place.

Negatively charged electrode is the anode where the process of oxidation takes place.

<u>So, the correct answer is - The cathode is the electrode where the reduction takes place.</u>

A sample containing 2.30 mol of Ne gas has an initial volume of 8.00 L. What is the final volume, in liters, when the following
marta [7]

Answer:

a. 4,00L

b. 16,00L

c. 12,31L

Explanation:

Avogadro's law says:

\frac{V_1}{n_1} =\frac{V_2}{n_2}

a. If initial conditions are 2,30mol and 8,00L and you lose one-half of atoms, that means you have 1,15mol:

\frac{8,00L}{2,30mol} =\frac{V_2}{1,15mol}

<em>V₂ = 4,00L</em>

b. If initial conditions are 2,30mol and 8,00L and you add 2,30mol, that means you have 4,60mol:

\frac{8,00L}{2,30mol} =\frac{V_2}{4,60mol}

<em>V₂ = 16,00L</em>

c. 25,0g of Ne are:

25,0g × (1mol / 20,1797g) = 1,24 moles of Ne. That means you have 2,30mol - 1,24mol = 3,54mol of Ne

\frac{8,00L}{2,30mol} =\frac{V_2}{3,54mol}

<em>V₂ = 12,31L</em>

I hope it helps!
