Types of Reactions
- Single Replacement (sr)- A type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound. Example: Li + NaCl = LiCl + Na
- Double replacement (dr)- A type of chemical reaction where two chemicals react and the Cations and anions of the two reactants switch places. Example: BaCl2 +MgSO4 = BaSO4 + MgCl2
- Combustiton Reaction- An exothermic reaction in which something reacts with oxygen. Example: C6H14 + O2 = CO2 + H2
- Decomposition Reaction- A type of reaction in which a single compound breaks down into two or more elements or new compounds. Example: CuCl2 = Cu + Cl2
- Synthesis Reaction- A type of chemical reaction where two or more simple substances combine to form a more complex product. Example: C + O2 = CO2
How to use activity series with Single Replacement
- Metal can replace another metal if it is above it on the activity series. EX: Li + NaCl -> LiCl + Na
Solubility Rules- A list of rules to see if a compound dissolves in water or not.
- Something is soluble if: It's a Nitrate, an Acetates, an Ammonium, and Group 1 salt.
- A Chloride, a Bromide, and an Iodide except for Silver, Lead, and Mercury (I).
- All fluorides except Group 2 (IIA), Lead (II), and Iron (III)
- All sulfates except Calcium, Strontium, Barium, Mercury, Lead (II), and Silver
- Something is insoluble if: All carbonates and phosphates except Group 1 (IA) and Ammonium
- All hydroxides except Group 1 (IA), 2 (IIA), and Ammonium
- All oxides except Group 1 (IA)
