Yes, and no. We all should know by know we do need the sun to survive, but we also need for energy is oxygen and the food we eat.
In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the <u>cathode</u>; the chemical change that occurs at this electrode is called <u>reduction</u>.
<h3>Define Electrolyte:-</h3>
An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.
<h3>Electrochemical cell </h3>
There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements
- The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
- The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
- A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
- Anode and cathode are connected by the conductor, which also completes the circuit.

Answer:
11460 years
Explanation:
0.693/t1/2 = 2.303/t log (No/N)
t1/2 = half life of the carbon
t = age of the fossil
No= amount of radioactive material originally present
N= amount of radioactive material present at time=t
No= mass of carbon + nitrogen = 5g
0.693/5730 = 2.303/t log (5/1.25)
1.21 ×10^-4 = 1.3866/t
t= 1.3866/1.21 ×10^-4
t= 11460 years
