Just gonna answer a few for you because the answers to these are relatively easy to research.
What "chemicals" have to be balanced in the body?~Dopamine
~Seretonin
~Gamma-aminobutyric acid
What other properties have to be balanced?~sympathetic nervous system
~endocrine
What does it mean to be balanced?~Homeostasis, also spelled homoeostasis
is the property of a system in which variables
are regulated so that internal conditions remain
stable and relatively constant. Examples of
homeostasis include the regulation of temperature
and the balance between acidity and alkalinity (pH).
It is a process that maintains the stability of the human
body's internal environment in response to changes in
external conditions.
Be more specific about what part of the body has to maintain pH.http://www.envirohealthtech.com/ph.htmHow does the amount of carbon dioxide affect pH and what mechanisms regulates that?~As with all waste products, carbon dioxide gets excreted into the blood. The blood carries carbon
dioxide to the lungs, where it is exhaled. As carbon dioxide accumulates in the blood, the pH of the
blood decreases (acidity increases). The brain regulates the amount of carbon dioxide that is exhaled
by controlling the speed and depth of breathing. The amount of carbon dioxide exhaled, and
consequently the pH of the blood, increases as breathing becomes faster and deeper. By adjusting
the speed and depth of breathing, the brain and lungs are able to regulate the blood pH minute by minute.

The brain is another organ that requires the right chemical balance otherwise the individual would experience thought disorders. The worst case scenario would be a complete psychiatric breakdown, resulting in an irreversible loss of neurons. Biochemical engineers working for pharmaceutical companies make a lot of money because they know how to treat a chemical imbalance in the brain. Antipsychotic medication can cost up to $1,000 for a one-month supply.
