27.3 C
calorimeter
An insulated container that is used to measure heat changes during a chemical or physical process.
calorimetry
The measurement of the transfer of heat into or out of a system during a chemical reaction or physical process.
carbohydrates
Monomers and polymers of aldehydes and ketones that have multiple hydroxyl groups attached.
carboxylic acid
An organic compound that contains the carboxyl functional group (−COOH).
catalyst
A substance that increases the rate of a chemical reaction by lowering the activation energy without being used
up in the reaction.
cathode
The electrode at which reduction occurs.
cathode ray
Glowing beam that travels from the cathode to the anode in a cathode ray tube.
cathode ray tube
Device in which an electric current is passed through gases at low pressure.
cation
A positively charged ion.
cell potential
The difference in reduction potential between the two half-cells in an electrochemical cell.
chain reaction
A reaction in which the material that starts the reaction is also one of the products and can start another
reaction.
chemical change
Change that produces matter with a different composition.
chemical equation
A representation of a chemical reaction that displays the reactants and products with chemical formulas;
multiple reactants or products are separated with a plus sign, while the reactants are separated from the
products with a yield arrow.
chemical equilibrium
The state of a system in which the rate of the forward reaction is equal to the rate of the reverse reaction.
chemical potential energy
The energy stored in the chemical bonds of a substance.
chemical property
Describes the ability of a substance to undergo a specific chemical change.
chemical reaction
Process that occurs when one or more substances is changed into one or more new substances.
chemical symbol
One- or two-letter designation of an element.
chemistry
The study of the composition of matter and the changes that matter undergoes.
closest packing
The most efficient arrangements for packing atoms, ions, or molecules in a crystal.
