The anode and cathode when plating an iron nail with zinc :

anode : zinc

cathode : iron nail

<h3>Further explanation</h3>

Electrolysis utilizes electrical energy to carry out non-spontaneous redox reactions. The ions in the solution flowed by an electric current

The electrolyzed substance is an electrolyte which can be in the form of a melt or a solution.

In the electrolytic cell the positive pole - the anode is the site of oxidation, whereas the negative pole - the cathode is the site of the reduction

Electrons (electricity) enter the electrolysis cell through the negative pole (cathode)

Electroplating is one of the applications of electrolysis. In the electroplating process, the metal to be plated as a cathode and the plating metal as an anode. Both electrodes are dipped in an electrolyte saline solution from the positive metal plating ion. In this electroplating process, the metal at the anode will oxidize and dissolve into metal ions. Then this ion will experience a reduction reaction and is deposited on the surface of the cathode.

 

The reaction that occurs in plating iron nail with zinc.

Cathode (Fe): Zn²⁺ (aq) + 2e⁻ ---------> Zn (s)

Anode (Zn): Zn (s) ----------> Zn²⁺ (aq) + 2e⁻

-------------------------------------------------- -----------

Zn (s) Anode -----> Zn (s) Cathode

The electrolyte used can be ZnCl₂

point)A chemist has 4.43 g of lithium carbonate and must make a 0.0600 mol/L solution.What volume of solution can be made?a) 0.0
ANTONII [103]

Explanation:

A chemist has 4.43 g of lithium carbonate and must prepare a 0.0600 mol/L (or 0.0600 M) solution. We have to find the volume of solution that can be made.

The molarity of a solution is defined like:

molarity = moles of solute/volume of solution in L

We already know the concentration of the solution (it is 0.0600 mol/L) and the volume is our unknown.

volume of solution in L = ?

molarity = 0.0600 mol/L

We still have to convert the mass of lithium carbonate into moles. To do that we will use the molar mass of the compound.

lithium carbonate = Li₂CO₃

mass of Li₂CO₃ = 4.43 g

molar mass of Li₂CO₃ = 73.89 g/mol

moles of Li₂CO₃ = 4.43 g * 1 mol/(73.89 g)

moles of Li₂CO₃ = 0.0600 moles

Finally we can replace the values in the formula and solve it for the volume of solution.

molarity = moles of solute/volume of solution in L

volume of solution in L = moles of solute/molarity

volume of solution in L = 0.0600 mol/(0.0600 mol/L)

volume of solution in L = 1.00 L

Answer: b) 1.00 L

If the temperature of gas is held constant describe the relationship between a gas volume of a gas pressure?
love history [14]
This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand.
