Chemical reaction
a solid that is produced as a result of a chemical reaction in solution
precipitate
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 reaction and the products
chemical equation
a substance or molecule that participates in a chemical reaction
reactant
the substance that forms in a chemical reaction
product
the law that states that mass cannot be created or deystoryed in ordinary chemical and physical changes.
law of conservation of mass
a reaction in which two suubstances combine to form a new compound
synthesis reaction
a reactions in which a single compound breaks down to form two or more simpler substances
decomposition reaction
a reaction in which one element ir eadical takes place of another wkement or radical in a compond
single-displacement
a reaction in which a gas, a solid precipate, or a molecular compund forms from exhange of ions between two componds
double displacement reaction
a chemical reaction in which heat is relised to the surroundings
exothermic reaction
a chemical reaction that requares heat
endothermic reaction
the law states that energy canot be created or deystoyed but can change from one form to another
law of conservation of energy
the minimum amount of energy required to stat a chemical reaction
activation energy
