| Question | Answer |
| Properties of covalent bonds | generally low melting/boiling point, generally low solubility, cannot conduct electricity in any state. |
| Naming compounds | Check whether metal, metalloid or non metal. Name accordingly then check states |
| Collision theory | Must collide, have sufficient energy in order to rearrange the electrons, and have correct orientation in order to allow the electrons to rearrange. |
| What is an acid? | A substance that releases H+ ions when dissolved in water. |
| Properties of acid | sour, pH less than 7, corrosive and turns blue litmus paper red. |
| Law of Conservation of Mass | Mass can neither be created nor destroyed in ordinary chemical and physical changes. Must start and end with the same mass in chemical equation/reactions. |
| Rate of reaction formula | =loss of reactant/time |
| concentration formula | =mass of solute(g)/volume of solution(L) |
| 1 ,2, 3, 4, 5 | mono, di, tri, tetra, penta |
| base | releases OH- ions when dissolved in water |
| Naming covalent bonds | furthest left and lowest on the period table first |
| Acid + Metal | salt + hydrogen Gas |
| Acid + metal hydroxide) | Salt + Water |
| Acid +Metal Carbonate) | Salt + Water + carbon Dioxide |
| Acid + Metal Hydrogen Carbonate) | Salt +Water+ Carbon Dioxide |
| Metal +oxygen | Metal Oxide (oxidation reaction) |
| Non Metal + Oxygen | Non metal oxide (oxidation reaction) |
| Ionic compound(aq) + Ionic compound(aq) | Ionic compound(s) + Ionic compound(aq) |
