| Question | Answer |
|---|---|
| This number equals the number of protons in an atom. | Atomic Number |
| What does the law of conservation of mass state? | Total mass of all reactants must equal the total mass of all the products. |
| Which of the properties of water listed in your notes are due to the polarity of the water molecule? | All of the properties of water. |
| These bonds are formed when electrons are shared. | Covalent Bonds |
| The charge for a neutron. | Neutral - no charge |
| Another term for reactions which are biosynthetic in nature. | Anabolic Reactions |
| The charge for a proton. | Positive |
| The 2 types of particles found in the core of an atom. | Protons and neutrons |
| Which type of biological reaction involves the uptake of water and ends up breaking down molecules? | Hydrolytic Reactions |
| Is a solution with a pH of 9 considered an acid, base or neutral? | Base |
| Diatomic nitrogen is held together by how many covalent bonds? | triple covalent bond |
| Another term for reactions which are degradative in nature. | catabolic reactions |
