(24 cards)
Colloid
A mixture that consist of tiny particles that are intermediate in size between those in solutions and the ones in suspensions and the ones that are in a liquid , solid , or gas .
Emulsion
Want mixture made up of two or more immiscible liquids in which one liquid is dispersed by another .
Solution
A homogenous mixture of two or more substances that are uniformly dispersed throughout a single phase .
Solute
Is the substance that dissolves in the solvent .
Solvent
The substance that the solute dissolves in
Alloy
Is a solid or a liquid mixture of two or more metals .
Hydrogen bonding
Intermolecular force that occurs when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule .
