| Question | Answer |
|---|---|
| organic chemistry | carbon chemistry |
| single bond | a covalent bond where 2 atoms share one pair of electrons |
| double bond | a covalent bond where 2 atoms share two pairs of electrons |
| ion | charged particle |
| acid | anything that increases the H+ concentration in water. |
| base | anything that increases the OH- (hydroxide) concentration in water. |
| buffer | compounds that can neutralize small amounts of acids and bases. |
| PH scale | a scale ranging from 0-14 that measures the acid-tidy & base-tidy of a solution. |
| 3 phases | solid liquid gas |
| 4 forms of energy | Electrical, nuclear, mechanical, and chemical. |
| polar molecule | a covalent bond with a partially positive and a partially negative side |
| reactant | the substance on the left side of the arrow in an equation (starting materials). |
| products | the substance on the right side of the arrow in an equation (finished product). |
| catalyst | a substance that lowers activation energy |
| activation energy | energy needed to start a reaction |
| enzyme | an organic catalyst Fits on top of molecule and allows it to break or bond |
| ionic compound | a molecule in which an atom gives it's electrons |
| covalent compound | a molecule formed when two atoms share 2 electron |
| Grade -1 17/17 In a covalent bond you have to share at least 2 electrons to make a bond. Also revise pH scale for spelling. |
