100
The term neutral indicates that a substance has a pH of...
What is 7?
100
When this element is present in a compound, it is considered to be organic.
What is carbon?
100
An organism's genetic information is stored in this macromolecule.
What is DNA?
200
The process by which atoms or groups of atoms in substances are reorganized into different substances.
What is a chemical reaction?
200
A positively charged subatomic particle.
What is a proton?
200
Substances with pH below 7.
What are acids?
200
These are the three elements found in carbohydrates.
What are carbon, hydrogen, and oxygen?
200
These types of organic molecules serve as the major energy source for humans and other multicellular organisms.
What are carbohydrates?

The energy needed to get a chemical reaction to proceed.
What is activation energy?
300
A negatively charged particle located outside the atom's nucleus.
