Basics
The science that deals with the composition, structures, and properties of matter and how matter changes under different conditions.
Is a change in the form or physical properties of a substance.
What is a physical change?
A stable, uniform mixture of two or more substances.
What is a solution?
Liquids that are mutually soluble, meaning that they can be mixed together to form solutions.
What is miscible liquids?
pH stands for this.
What is potential hydrogen?
The simplest form of chemical matter and contains only one type of atom.
What is an elements?
Is a change in the chemical composition or makeup of a substance.
What is a chemical change?
The substance that is dissolved in a soltuion.
What is a solute?
Liquids that are not capable of being mixed together to form stable solutions.
What is an immiscible liquid?
This level represents the pH of a neutral solution.
What is 7?
The basic unit of matter, with a nucleus at the center surrounded by negatively charged electrons.
What are atoms?
Characteristics that can be determined without a chemical reaction and do not involve a chemical change in the substance.
What are physical properties?
The substance that dissolves the solute and makes the solution.
What is a solvent?
Substances that allow oil and water to mix, or emulsify.
What are surfactants?
What is an exothermic reaction?
A chemical combination of two or more atoms in definite proportions.
What are molecules?
Characteristics that can be determined only by a chemical reaction and involve a chemical change in the substance.
What are chemical properties?
Unstable physical mixtures of undissolved particles in a liquid.
What is a suspension?
The water loving head of a surfactant molecule
What is hydrophilic?
What is an oxidizing agent?
What are compound molecules?
A chemical combination of matter in definite proportions.
An unstable physical mixture of two or more immiscible substances plus a special ingredient called an emulsifier.
What is an emulsion?
The oil loving tail of a surfactant molecule.
What is lipophilic?
A chemical reaction that requires the absorption of energy or heat from an external source for the reaction to actually occur.
What is an endothermic reaction?
