These are chemical species that are present in a chemical reaction, but do not participate in it.
What are spectator ions?
This is the name of the phase change that occurs when a solid is converted directly to a gas.
What is sublimation?
This is the volume that one mole of gas occupies at STP.
What is 22.4 L?
This is a chemical species, like water, that can act either as an acid or a base.
What is an amphoteric species.
This is the oxidation number of oxygen in a compound (not a peroxide).
What is -2?
This is a substance that only partially ionizes in solution and is therefore a poor conductor of electricity.
What is a weak electrolyte?
These are observable changes that accompany chemical reactions.
What are driving forces?
This is an ionic compound with water included as “⋅xH2O”, where x is the number of water molecules per formula unit of the salt.
What is a hydrate?
This is the solution in a titration with a known volume but an unknown concentration.
What is the analyte?
This is the species that promotes reduction in other species by donating electrons.
What is the reducing agent?
This is a solution that contains more than the maximum amount of solute that can be dissolved under a set of given conditions because it was saturated at a higher temperature and/or lower pressure.
What is a supersaturated solution?
This describes the energy change when bonds are broken.
What is endothermic (requiring energy input)?
This is the maximum amount of a product that can be made under perfect conditions.
What is theoretical yield?
This is the conjugate base that is formed when acetic acid (CH3COOH) reacts with water.
What is CH3COO- (acetate)?
This is the species that is oxidized in the following reaction:
Zn (s) + 2 HCl (aq) --> ZnCl2 (aq) + H2 (g)
What is Zn?
This symbology indicates in a chemical reaction that one of the reactants only partially dissociates in solution.
What are reversable or double-headed arrows?
This is the type of change that occurs when an ionic salt dissolves in water.
What is a physical change?
This is the mass of aluminum necessary to produce 0.483 mol of hydrogen gas at 25 *C and 1.00 atm according to the following equation:
2 Al + 6 HCl --> 2 AlCl3 + 3 H2.
What is 8.69 g?
This is the anion in each strong base that must be memorized for AP Chemistry.
What is hydroxide (OH-)?
This is the oxidation number of manganese in MnO4-.
What is +7?
This is the net ionic equation for the following reaction: a solution of ammonium carbonate reacts with a solution of silver nitrate, forming a white silver carbonate precipitate.
What is: 2 Ag+(aq) + CO32-(aq) → Ag2CO3(s)
This is the type of change that occurs when a mixture is separated using columnar chromatography.
