chapter 2 chemical reactions Flashcards
chemical reactions
the process by which one or more substances change to produce one or more different substances.
chemical reactions
the process by which one or more substances change to produce one or more different substances.
precipitate
a solid that is produced as a result of a chemical reaction in solution.
chemical formula
a combination of chemical symbols and numbers to represent a substance.
chemical equation
a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.
reactant
a substance or molecule that participates in a chemical reaction.
product
the substance that forms in a chemical reaction.
law of conservation of mass
the law that states that mass cannot be created or destroyed in ordinary chemical and physical changes.
synthesis reaction
a reaction in which two or more substances combine to form a new compound.
precipitate

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.
single-displacement reaction
a reaction in which one element or radical takes 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 exchange of ions between two compounds.
exothermic reaction
a chemical reaction in which heat is released to the surroundings.
endothermic reactions
a chemical reaction that requires heat
law of conservation of energy
the law that states that energy can not be created or destroyed but can be changed from one form to another
activation energy
the minimum amount of energy required to start a chemical reaction.
inhibitor
a substance that slows down or stops a chemical reaction.
