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.

Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration

Answer:
A = 8
B = 8
C = Oxygen (O)
D = 26
E = 30
F = Iron (Fe)
Explanation:
protons neutrons atomic number mass number element
A 7 B 15 C
D E 26 56 F
mass number = protons + neutrons
E = 56 - 26 = 30
A = 15 - 7 = 8
protons = atomic number
B = 8
D = 26
From atomic number:
C = Oxygen (O)
F = Iron (Fe)
Answer:
.
Explanation:
Given that
MM''= a cos(fL)
We know that all trigonometric function are dimensional less.So fL should be dimension less quantity.
Property Dimension
Length L
Mass M
Force 
Acceleration 
Velocity
Torque
Time 
So in the given question ,dimension of L is L so the dimension of f will become
.
Answer:
28g/mol
2 moles of nitrogen are present
Explanation:
The molar mass is defined as the mass of a chemical when 1 mole of this substance is present and is used to convert mass of the substance to moles or vice versa. Is widely used in stoichiometry problems.
1 atom of nitrogen has a molar mass of 14g/mol. N₂(g) -The molecule that contains 2 atoms of nitrogen- has a molar mass of 28g. That is 28g/mol.
56g of N₂ are:
56g * (1mol / 28g) =
<h3>2 moles of nitrogen are present</h3>
