Chemical Reactions by Mind Map: Chemical Reactions

1. AB=(heat)> A+B

2. A + BX → AX + B

2.1. A and B are different metals

3. A DR reaction will only occur, if one the pairs of ions will combine and leave the solution. That means it forms a solid precipitate, a gas or water.

4. Occur based on reactivity series

5. Higher Temp, more kinetic energy (move faster), increase in the rate of reaction

6. Uses

6.1. Rearrangement of atoms (Chemical Reaction)

6.2. Separates Compounds

6.3. Obeys the Law of Mass Conservation

6.3.1. Balance Equations

6.3.1.1. Types and number of atoms are the same on each side of the equation

7. Evidence

7.1. Color Changes

7.2. Heat/ Light released/ absorbed

7.3. Formation of gas/ precipitate

7.3.1. Precipitate: does not dissolve, solid at room temp

8. Double Displacement

8.1. AB+CD => AD+BC

8.1.1. The cations and anions switch elements

8.2. 2 compounds to start 2 compounds produced

8.3. Nature of the product, determined by solubility table

9. Single Displacement

10. Synthesis

10.1. A+B=> AB

10.2. Combination of 2 reactants, only one product

11. Decomposition

11.1. Breaking down of a compound into its simple starting reactants (into elements)

12. Neutralization Reaction

12.1. Acid+Base=> Water+Salt

12.2. Ex//Brushing teeth with the use of toothpaste, toothpaste is an alkaline substance that neutralizes the acid formed from the decomposing food you ate all day that happened to get stuck to your teeth
