100
This number determines the way atoms combine in compounds.
What is oxidation number?
100
The coefficients in front of compounds in a balanced equation represent these.
What are molar ratios?
100
These electrons are given up by atoms in order to become positive ions.
What are valence electrons?
100
This symbol indicates a change in temperature.
What is ∆T?
100
This is expressed by moles of solute over kilograms of solvent.
What is molality?
200
This scientist created the periodic table in which elements are arranged by atomic number.
Who is Henry Moseley?
200
This describes a compound disolved in water.
What is aqueous?
200
When the number of this subatomic particle is changed, an atom does not become an isotope or ion.
What is a proton?
200
This measure of energy uses the symbol "J".
What is a joule?
200
This describes a solution that is consistent throughout.
What is homogeneous?
300
This is the name of the second to last group on the periodic table.
What are halogens?
300
In this type of reaction, oxygen and carbon dioxide are produced.
What is a combustion reaction?
300
Usually a non-metal or metalloid, this ion is negative.
What is an anion?
300
If a reaction is cool to the touch, it is this.
What is endothermic?
300
This is the process all supersaturated solutions must go through.
What is cooling?
400
This element has the greatest atomic radii.
What is Francium?
400
The arrow in a chemical equation is called this.
What is a yield sign?
400
In these reactions unstable isotopes of certain elements are broken down into smaller, more stable isotopes.
What is nuclear fission?
400
Sometimes expressed as cal/gºC, this describes how substances respond to energy.
What is specific heat?
400
Along with agitation, mass of solute, and heat, this affects the rate of dissolution.
What is surface area of solute?
500
This family contains the least reactive of all and metalloids.
What is the Carbon family?
500
This describes the two ions in a reaction that do not change.
What are spectator ions?
500
These are the least likely elements to ionize.
What are noble gasses?
500
This energy is stored in many dormant reactions, such as batteries.
What is chemical energy?
500
Along with "-ose", this suffix means that a compound has a van't hoff factor of one.
What is "-ol"?
