Chemical Structure
chemistry
what is the science that deals with the compositions, structures, and properties of matter and how matter changes under different condition.
protons
what are subatomic particles with a positive charge
physical change
what is a change in the form or physical properties of a substance, without a chemical reaction or the creation of a new substance
physical mixture
what is a physical combination of matter in any proportion
immiscible
what is when liquids are not capable of being mixed together to form stable solutions
matter
what is any substance that occupies space and has mass
neutrons
what are subatomic particles with no charge
chemical change
what is a change in the chemical composition or makeup of a substance
solution
what is a stable, uniform mixture of two or more substances
suspension
what are unstable physical mixtures of undissolved particles in a liquid
element
what is the simplest form of chemical matter and contains only one type of atom
molecule
what is a chemical combination of two or more atoms in definite proportions
physical properties
what are characteristics that can be determined without a chemical reaction and do not involve a chemical change in the substance
solute
what is the substance that is dissolved in a solution
emulsion
what is an unstable physical mixture of two or more immiscible substances plus a special ingredient called an emulsifier
atoms
what are the basic unit of matter
elemental molecule
what is a molecule containing two or more atoms of the same element in definite proportions
chemical properties
what are characteristics that can be determined only by a chemical reaction and involve a chemical change in the substance
solvent
what is the substance that dissolves the solute and makes the solution
emulsifier
what is an ingredient that brings two normally incompatible materials together and binds them into a uniform and fairly stable mixture
electrons
what are subatomic particles with a negative charge
compound molecules
what are chemical combinations of two or more atoms of different elements in definite proportions
pure substances
what is a chemical combination of matter in definite proportions
miscible
what are when liquids are mutually soluble
surfactants
what are substances that allow oil and water to mix, or emulsify
