Unit 8 Quizs

Reactants

• The substances produced at the end of a chemical reaction

• The starting substances at the beginning of a chemical reaction

• The catalysts that speed up a chemical reaction

• The byproducts formed during a chemical reaction

Combustion reaction

• Oxygen combines with a substance and releases energy in the form of heat and light.

• A reaction where two or more substances combine to form a new substance.

• A process that absorbs energy and does not produce heat or light.

• A reaction that occurs only in the absence of oxygen.

Single-replacement reaction

• A reaction where two compounds exchange ions.

• A reaction in which atoms of one element replace the atoms of another element in a compound.

• A reaction that involves the combination of two or more substances to form a new compound.

• A reaction that breaks down a compound into its individual elements.

Products

• Substances that are formed during a chemical reaction

• Elements that are used in a chemical reaction

• Reagents that are consumed in a chemical reaction

• Catalysts that speed up a chemical reaction

spectator ions

• Ions that do not participate in a chemical reaction

• Ions that are involved in the reaction

• Ions that increase the rate of reaction

• Ions that are produced as a byproduct

Synthesis reaction

• A chemical reaction in which two or more substances react to produce a single product.

• A reaction where a single compound breaks down into two or more simpler substances.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs when a substance combines with oxygen to produce heat and light.

net ionic equations

• Ionic equations that include only the particles that participate in the reaction.

• Equations that show all ions present in a solution.

• Equations that balance the number of atoms on both sides.

• Ionic equations that do not include any ions.

Double-replacement reaction

• A reaction where one element replaces another in a compound.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs only in gaseous states.

• A reaction that produces a single product from multiple reactants.

Decomposition reaction

• A reaction where two or more compounds combine to form a single compound.

• A chemical reaction in which a single compound breaks down into two or more elements or new compounds.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs only in the presence of a catalyst.

coefficient

• A number written in front of a reactant or product in a chemical equation.

• A type of chemical bond between two atoms.

• The total number of atoms in a molecule.

• A measure of the concentration of a solution.
