2
double replacement reactions
A type of chemical reaction where two ionic compounds exchange ions to form two new compounds. The cations and anions switch places. Also known as metathesis reactions.
New cards
3
synthesis reactions
A type of chemical reaction where two or more substances combine to form a more complex product.
New cards
4
decomposition reaction
type of chemical reaction where a single compound breaks down into two or more simpler substances.
New cards
5
oxidation-reduction reaction
Type of chemical reaction where electrons are transferred between two species. One species loses electrons while the other gains electrons
New cards
6
formation reactions
A formation reaction that forms one mole of a compound from its constituent elements in their standard states.
New cards
7
half reactions
A chemical equation that represents either oxidation or reduction. It only shows the transfer of electrons and does not include the full chemical equation.
New cards
8
net ionic equations
a chemical equation that shows only the species that participate in a reaction. It excludes spectator ions, which do not participate in the reaction.

Solubility Rules
Guidelines for predicting solubility of compounds in a solvent based on their chemical properties. "Like dissolves like" principle used, meaning compounds with similar polarities dissolve in each other.
New cards
10
polyatomic ion
charged species that contain two or more atoms covalently bonded together. They act as a single unit and carry a net charge due to the loss or gain of electrons.
New cards
11
monoatomic ions
A charged particle with a single atom. Formed when an atom gains or loses electrons.
New cards
12
addition reactions
A type of chemical reaction where two or more molecules combine to form a larger molecule with no atoms left over.
New cards
13
Neutralization Reactions
A chemical reaction between an acid and a base that results in the formation of salt and water.
New cards
14
combustion reaction
A chemical reaction that involves the rapid combination of oxygen with a fuel source, resulting in the release of heat and light energy.
