There are 5 types of chemical reactions to know!
1. Single displacement
2. Double displacement
3. Synthesis
4. Decomposition
5. Combustion
• happens when a single element is replaced by a different element from an ionic compound
A + BC —> AB + C
Example: Cu + AgCl —> CuCl + Ag
1. Single Displacement
• occurs when ionic compounds switch their metals
AB + CD —> CB + AD
Example: AgNO3 + NaCl —> NaNO3 + AgCl
2. Double Displacement
Single or Double?Zn + HCl —> H2 + ZnCl
copper chloride + aluminum —> aluminum chloride + copperAgNO3 + NaCl —> NaNO3 + AgCl
Cu + AgCl —> CuCl + Agmagnesium bromide + zinc chloride —> magnesium chloride + zinc bromide
2CuCl + CaO —> CaCl2 + Cu2O
Zn + NaCl —> ZnCl2 + Na
CuNO3 + K —> Cu + KNO3
NaOH + KNO3 —> NaNO3 + KOH
NaCl + F2 —> NaF + Cl2
calcium + hydrogen chloride —>
hydrogen + calcium chloride

1.Obtain the dropper bottles and spot plate. 2.Place 5 drops of one chemical in a depression of the spot plate. 3.Place 5 drops of second into the same depression. 4.Observe and record any changes. (DID IT FORM A PRECIPITATE?) 5.Repeat this procedure in different depressions for each combination in the observation chart. 6.Dispose of the mixtures as instructed by the teacher.
