Three particles that make up atoms.
What are protons, neutrons, and electrons.
What is a mixture?
These are the 3 major elements of life.
What are carbon, hydrogen, and oxygen.
This process changes one set of chemicals into another.
What is a chemical reaction?
A substance that speeds up the rate of a chemical reaction.
What is a catalyst?
The place where protons and neutrons are stored.
What is the nucleus?
When sugar is dissolved in water, water is referred to as this.
What is a solvent?
These are a large and varied group of biological molecules that are generally not soluble in water.
What are lipids?
What is activation energy?
Any compound that forms H+ ions in solution.
If carbon has 6 protons, carbon-16 contains this many neutrons.
What is 10?
While preparing a cell culture, a scientist places a colony of bacteria into distilled water and stirs it. The mixture of water and living cells is best referred to as this.
What is a suspension?
Carbon is special compared to other elements because of this.
What is the ability to bond with many elements?
In chemical reactions, this happens to atoms.
What is rearrangement?
This is formed when one or more electrons are transferred from one atom to another.
What is an ionic bond?
These have unstable nuclei and break down at a constant rate over time.
What are radioactive isotopes?
What is basic?
These in a polymer may be identical.
What are monomers?
These take up chemical reactions that take place in cells.
What are enzymes?
Single sugar molecules are also known as these.
What are monosaccharides?
This type of ion is formed when an atom loses electrons.
What is positive?
A molecule is polar when there is an uneven distribution of this between its atoms.
What are electrons?
Covalent bonds called peptide bonds link these together to form a polypeptide.
What are amino acids?
Two types of energy changes during a chemical reaction.
What are releasing or absorbing energy?
Measurement system that chemist devised.
What is the pH scale?
