balancing equations
According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants.
Therefore, the amount of the atoms in each element does not change in the chemical reaction.
As a result, the chemical equation that shows the chemical reaction needs to be balanced.
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.

Balancing Chemical Equations
In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3).
The reactants are nitrogen and hydrogen, and the product is ammonia.
If we look at this equation, we can see that the equation is not balanced.
Balancing Chemical Equations Example
The equation is not balanced because in the reactants side, there are 2 nitrogen (N) atoms and 2 hydrogen (H) atoms.
In the products side, there are 1 nitrogen (N) atoms and 3 hydrogen (H) atoms.
The number of the atoms is not balanced on both sides.
To balance the chemical equation above, we need to make use of coefficients.
A coefficient is a number that we place in front of a chemical formula.
In the chemical equation, to make the number of nitrogen (N) atoms equal on both sides, first, we place a coefficient of 2 in front of NH3.
-
Once we do that, the number of nitrogen (N) atoms on both sides is balanced.
However, the number of hydrogen (H) atoms is not balanced on both sides. We need to make use of another coefficient in front of H2. This time, we put a coefficient of 3 in front of H2 to balance the chemical equation.
-
The equation above is now balanced.There are 2 nitrogen (N) atoms and 6 hydrogen (H) atoms on both the reactants and products side. Since there is no coefficient in front of N2, that means the coefficient is equal to 1.

Respiration
Respiration occurs in all living cells
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
The chemical equation for energy is 6O2+C6H12O=ATP+6CO2+6H20
oxygen+sugars=energy +carbon dioxide +water

Plasma is what is left in the blood it contains hormones, CO2, little proteins . Plasma can be used to cure some genetic diseases.
white blood cells
white blood cells as your immunity cells. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.
