4. A galvanic cell is formed when two metals are immersed in solu- tions differing in concentration 1 when two different metals
Vanyuwa [196]

A galvanic cell is formed when two metals are immersed in solutions differing in concentration, when two different metals are immersed.

<h3><u>What is a </u><u>Galvanic</u><u> </u><u>cell</u><u> ?</u></h3>
  • In order to provide a pathway for the flow of electrons along that wire, the galvanic cell makes use of the ability to split the flow of electrons during the oxidation and reduction processes.
  • It forces a half-reaction and connects each to the other with a wire.
  • A galvanic cell is an electrochemical device that converts chemical redox reaction energy into electrical energy.
  • Electrically, it has a potential of 1.1 V. Oxidation takes place at the anode, which is a negative plate in galvanic cells. It is a positive plate where the reduction happens.
  • An electrochemical device called a galvanic cell transforms chemical energy's free energy into electrical energy. A photogalvanic cell produces species that are photochemically reactive.

During the nuclear fission process, the transformation between a parent and daughter isotope involves a a release of neutrons an
denis-greek [22]

Answer:

The energy harnessed in nuclei is released in nuclear reactions. Fission is the splitting of a heavy nucleus into lighter nuclei and fusion is the combining of nuclei to form a bigger and heavier nucleus. The consequence of fission or fusion is the absorption or release of energy.

A chemist prepares a solution of iron chloride by measuring out 0.10 g of FeCl2 into a 50. mL volumetric flask and filling to th
Tanya [424]

<u>Answer:</u> The molarity of anions (Cl^-) in the solution is 0.0316 M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Given mass of iron (II) chloride = 0.10 g

Molar mass of iron (II) chloride = 126.75 g/mol

Volume of solution = 50 mL

Putting values in above equation, we get:

\text{Molarity of iron (II) chloride}=\frac{0.10\times 1000}{126.75\times 50}\\\\\text{Molarity of iron (II) chloride}=0.0158M

1 mole of iron (II) chloride produces 1 mole of Fe^{2+} ions and 2 moles of Cl^- ions

So, concentration of chloride ions (anions) in the solution = (2\times 0.0158)=0.0316M

Hence, the molarity of anions (Cl^-) in the solution is 0.0316 M
