Chapter 6 Flashcards
Reactant
A reactant is a substance or molecule that participates in a chemical reaction.
Product
A product is a substance that forms in a chemical reaction.
Chemical energy
The energy released when a chemical compound reacts to produce new compounds.
Exothermic reaction
A chemical reaction in which heat is released to the surroundings. Isooctane-oxygen
Endothermic reaction
A chemical reaction that requires heat. Hydrated barium hydroxide and ammonium nitrate
Synthesis reaction
A reaction in which two or more substances combine to form a new compound
Decomposition reaction
A reaction in which a single compound breaks down to form two or more simpler substances
Electrolysis
The process in which an electric current is used to produce a chemical reaction, such as the decomposition of water.
Combustion reaction
The oxidation reaction of an organic compound, in which heat is released
Single-displacement reaction
A reaction in which one element or radical takes the place of another element or radical in a compound.
Double-displacement reaction
A reaction in which a gas, a solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds.
Oxidation reduction reaction
An oxidation reduction reaction is a type of chemical reaction that involves a transfer of electrons between two species.
Radical
A radical is an atom, molecule, or ion that has unpaired valence electrons
Reduced
A reduction is a chemical reaction that involves the gaining of electrons.
Oxidized
Combine or become combined chemically with oxygen.
Chemical equation
The symbolic representation of a chemical reaction in the form of symbols and formula.
Mole ratio
The ratio of moles of one substance to the moles of another substance
Coefficient
A number or symbol multiplied with a variable or an unknown quantity in an algebraic term.
Law of Conservation of Mass
It states that mass in an isolated system is neither created nor destroyed.
Law of Definite Proportions
It states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.
Catalyst
The increase in the rate of a chemical reaction due to the participation of an additional substance.
Enzyme
A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction
Substrate
A substance or layer that underlies something or on which some process occurs in particular
Chemical equilibrium
It is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.
