Uses
- Rearrangement of atoms(Chemical Reaction)
- Obeys the Law of Mass Conservation
- Balance Equations
- Types and number of atoms arethe same on each side of theequation
Evidence
- Heat/ Light released/ absorbed
- Formation of gas/ precipitate
- Precipitate: does not dissolve,solid at room temp
Higher Temp, more kinetic energy
Neutralization Reaction
-The best example is brushing the teeth. The alkaline solution helps in removing the food from the teeth
Decomposition
- Breaking down of a compound into itssimple starting reactants (intoelements)
Occur based on reactivity series
A + BX → AX + B
- A and B are different metals
Synthesis
- Combination of 2 reactants,only one product
DR reaction will occur and will form a solid precipitate, a gas or water.
Double Displacement
- AB+CD = AD+BC
- The cations and anions switchelements
- Nature of the product,determined by solubility table
