Rechargeable batteries use a reversible reaction medium to convert electrical current to a form of chemical energy which can be stored for future use.
<h3>
What is a rechargeable battery?</h3>
A rechargeable battery is a type of battery that can be charged many times by passing electric current through the cells in a reversible reaction.
<h3>How does recahargeable battery store energy?</h3>
When electrical energy from an outside source is applied to a secondary cell (reachargeable battery), the negative to positive electron flow that occurs during discharge is reversed, and the cell's charge is restored. This process is called reversible reaction.
Thus, rechargeable batteries use a reversible reaction medium to convert electrical current to a form of chemical energy which can be stored for future use.

Answer:
x=30
Explanation:
I will try to explain with a drawing.
This is a rule of three.
If you are wondering what the rule of three is. It's when u have 3 informations and you solve.
about 30 kilometers per second
At what speed does the Earth move around the Sun? (Beginner) Short version: Earth's average orbital speed is about 30 kilometers per second. In other units, that's about 19 miles per second, or 67,000 miles per hour, or 110,000 kilometers per hour (110 million meters per hour).
Hope This Helps! Have A Nice Day!!
C. 2
2H_2O + <u>2e</u>^(-) → H_2 + 2OH^(-)
2Cl^(-) → Cl_2 + <u>2e</u>^(-)
2H_2O +Cl^(-) + <u>2e</u>^(-) → H_2 + Cl_2 + 2OH^(-) + 2e^(-)
2H_2O +2Cl^(-) → H_2 + Cl_2 + 2OH^(-)
This is a <em>redox reaction</em> in which two chloride ions transfer two electrons to two molecules of water.
