| 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 "
