Chemical Reactions

AB=(heat)> A+B

A + BX → AX + B

A and B are different metals

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.

Occur based on reactivity series

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

Uses

Rearrangement of atoms (Chemical Reaction)

Separates Compounds

Obeys the Law of Mass Conservation

Balance Equations, Types and number of atoms are the same on each side of the equation

Evidence

Color Changes

Heat/ Light released/ absorbed

Formation of gas/ precipitate

Precipitate: does not dissolve, solid at room temp

Double Displacement

AB+CD => AD+BC

The cations and anions switch elements

2 compounds to start 2 compounds produced

Nature of the product, determined by solubility table

Single Displacement

Synthesis

A+B=> AB

Combination of 2 reactants, only one product

Decomposition

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

Neutralization Reaction

Acid+Base=> Water+Salt

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
