What is Matter?
One of three forms - solid, liquid, or gas - which every substance is capable of attaining.
What is Phase?
A measurement of how much solute exists within a certain volume of solvent.
What is Concentration?
The random motion of molecules from an area of high concentration to an area of low concentration.
What is Diffusion?
An explanation or representation of something that cannot be seen.
What is a Model?
A change that affects the appearance but not the chemical makeup of a substance.
What is Physical Change?
A membrane that allows some molecules to pass through but does not allow other molecules to pass through.
The tendency of a solvent to travel across a semipermeable membrane into areas of higher solute concentration.
What is Osmosis?
A collection of atoms that all have the same number of protons.
What is an Element?
A change that alters the makeup of the elements or molecules of a substance.
What is Chemical Change?
A substance that alters the speed of a chemical reaction but is not used up in the process.
What is a Catalyst?
Simple carbohydrates that contain 3-10 carbon atoms.
What are Monosaccharides?
Chemicals that result from atoms linking together.
What are Molecules?
A bond that links amino acids together in a protein.
What is a Peptide Bond?
Breaking down complex molecules by the chemical addition of water.
What is Hydrolysis?
Carbohydrates that are made up of two monosaccharides.
What are Disaccharides?
Two different molecules that have the same chemical formula.
What are Isomers?
A strong attraction between hydrogen atoms and certain other atoms (usually oxygen or nitrogen) in specific molecules.
What is a Hydrogen Bond?
A chemical reaction in which molecules combine by removing water.
What is Dehydration Reaction?
Carbohydrates that are made up of more than two monosaccharides.
What are Polysaccharides?
