Document Summary
Oxidation: oxidation number increases; reduction: oxidation number decreases (remember: oxidation is loss of electrons; reduction is gain of electrons) Half-reaction: a reaction that ends with a charge; only half of a redox reaction (either oxidation or reduction not both) Combination reaction: two substances turn into one, more complicated, substance: not a redox reaction; charge remains the same. Decomposition reaction: one complicated substance breaske down into two, simple, substacnes. Combustion reaction: typically produces a flame, water, carbon dioxide. Displacement reaction: single-replacement ; an element is displaced from original compound; one element is replaced by another in a reaction (a + bc= ac + b) Concentration: how much solute dissolved into solution: many reactions occur in aqueous solutions. Molarity: molar concentration (m); moles of solute per liter of solution m/l. Diluted: lower concentration with more solvent and same number of moles. Quantitative analysis: amount of a substance present in a material.
