| empirical formula key | 1. FIND THE RATIO!!! RATIO IS KEY [smaller product mass] divided by [substance mass] 2. then find the moles of each substance after you've figured out the ratio 3. then find the ratio of each mole to the smallest mole number! this will reveal! |
| explain the reaction types 1) single displacement (single replacement) 2) double displacement (double replacement) | name the reaction type 1) A+BC --> AC + B a lone ion changes from one element to another "hoe-down, one partner is alone" 2) AB + CD --> AD + CB two anions each switch cations "do si do dance - double displacement, both partners switch " |
| explain reaction types 1) synthesis reaction AKA _______ 2) decomposition reaction | name reactions 1) A + B ---> AB { AKA combination reaction } 2) AB ---> A + B |
| Alkali metals | Lithium Sodium Potassium |
| Diatomic molecules | GASES H N O F Cl ... H2, N2, O2, F2, Cl2 |
