Chapt 3-Classification of Matter
Has identical properties throughout
Matter that has parts with different properties
Matter with two or more substances mixed together but not chemically combined
'Least mixed' of all mixtures. Mixture that doesn't appear to be the same throughout.
'Well mixed'. Mixture that appears to be the same throughout. (Particles are very small and not easily recognized)
'Best mixed'. Type of homogeneous mixture formed when one substance dissolves into another
Metal solutions where solids are dissolved into solids
Made of only one kind of material with definite properties. (Homogeneous matter)
The simplest pure substance. They cannot be broken down into simpler substances. (Beware: Not all pure substances are elements)
The smallest particle of an element with all of the same properties.
Representation of elements. (If two letters make up a symbol, the 1st letter is capitalized followed by a lower case letter)
Two or more elements chemically combined. (Ex. Sugar, Oxygen, Carbon Dioxide)
Two or more atoms chemically bonded together. The smallest part of a compound that has all the properties of the compound.
Combinations of chemical symbols. Most represent compounds.
Small number written to the right side of an element in a chemical formula.
Description of a chemical reaction using symbols.
The number placed in front of (left side) the chemical symbol in order to balance the equation.
Substance that does the dissolving
Substance that is dissolved in the solution
Substance that doesn't dissolve in water (oil)
Substance that will dissolve in water (sugar, etc)
Heterogeneous mixture that can separate over time, generally cloudy or with floating particles that are visible to the eye (You can filter out particles)
Particle sizes are between a solution and a suspension (particles cannot be filtered out) Ex. Fog (It will scatter light)
