Chapter 2 Flashcards
The process by which one or more substances change to produce one or more different substances.
Chemical Reation
A solid that is produced as a result of a chemical reaction in a solution
Precipitation
A combination of chemical symbols and numbers to represent a substance
Chemical formula
A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
Chemical equation
A substance or molecule that forms in a chemical reation
Reactant
The substance that forms in a chemical reaction
Product
The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes
Law of conservation of mass
A reaction in which two or more substances combine to form a new compound
Synthesis reaction
A reaction in which a single compound breaks down to form two or more simpler substances
Decomposition reaction
A reaction in which one element or radical takes the place of another element or radical in a compund
Single-displacement reaction
A reation in which a gas, a solid, precipitate, or a molecular compound forms the exchange of ions between two compounds
Double-displacement reation
A chemical reaction in which heat is released to the surrondings
Exothermic
A Chemical reaction that requires heat.
Endothermic reaction
The law that states that energy can not be created or destroyed but can be changed from one to another
Law of Conservation of energy
The minimum amount of energy required to start a chemical reaction
Activation Energy
