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.

According to Dalton's Atomic Theory, the individual elements making up the compound has a fixed ratio. This law is known as the Law of Definite Proportions. Obeying this law, the number of hydrogen to oxygen should be a constant, so we can use ratio and proportion.
The ratio can be determined from the molecular formula of methyl tert-butyl ether: <span> C5H12O. This is the correct molecular formula of the compound. To check, try searching it in the internet. Its structural formula is drawn in the attached picture. From the molecular formula, we can see that there are 5 carbons in every 12 hydrogens and in every 1 oxygen. So, the hydrogen to oxygen ratio is 12/1. Applying ratio and proprotion,
12/1 = </span><span>0.0723 moles of hydrogen/x, where x is the amount of moles oxygen. Solving for x,
x = 0.006025 moles of oxygen</span>
