Matter Chapter 3, Mixtures, Elements, and Compound Flashcards
Mixture
Matter that consists of two or more substances mixed together but not chemically combined. Also the substances that make up a mixture have properties.
Heterogeneous Mixture
A mixture that does not appear to be the same throughout. The particles in it are large enough to be seen and saeperated from the others particles
Homogeneous Mixture
Is a mixture that appears to be the same throughout.
Colloid
It is a homogeneous mixture in which the particles are mixed together but not dissolved. Example: whip cream, clouds
Solution
Is the type of homogeneous mixture formed when one substance devolves in another.
Solute
The substance in solutions that is dissolved.
Solvent
The substance that does the dissolving.
Soluble
a substance that dissolves in water.
Insoluble
A substance that doesn’t dissolve in water.
Soulbility
The amount of a solute that can be dissolved in a solvent at a temperature.
Alloy
It is metal solutions like brass is an alloy of copper and zinc.
Pure Substance
All particles that make up a substance are one type of material and have definite properties.
Element
Elements are the simplest of pure substances.
Atom
The smallest particle of an element that has the properties of that element.
Chemical Symbols
Are the shorthand way of representing the elements.
Compound
Is a pure substance made of more than one element. Two or more is chemically combined.
Molecule
Two or more atoms that is chemically bounded together.
Chemical Formula
Combinations of chemical symbols are called chemical formulas.
Subscript
Small numbers to the lower of a chemical which tells how many atoms of that type.
Chemical Equation
A chemical equation tells molecules are in a chemical reaction and how many molecules are in a chemical reaction.
Coefficient
A coefficient is a number added to the left of a molecule in an equation.
