Concentration
Concentration is the ratio of solute in a solution to either solvent or total solution.
Concentration Formula: M = N/V

Reagents
Limiting Reagents
The reactant that is used up completly in a reaction is called a limiting reagent. They are substances that are completely used up in the completion of a chemical reaction.
Anions

Negative
Gain Electrons
An anion is as an atom that is negatively charged
Cations
An cation is an atom or molecule that is positively charged

Mixtures
Heterogeneous
Homogenous
A mixture is composed of one or more pure substances in varying composition
A small spot of a soluble mixture is placed on the paper. The solvent carries a mixture up the paper. Different components of the mixture have different relative affinities to the stationary and mobile phases and so travel up the paper at different speeds. This separates the components.
Flame Test
Atoms and their excited state
An atom or ion is excited by heating it to high temperatures, the electrons are promoted from their normal unexcited state into higher orbitals.
