Document Summary
Atoms rearrange, transforming the original substance unto different substances: physical change. No change in composition: chemical property. Property that a substance displays only by changing its composition (i. e. flammability: physical property. Property that a substance displays without changing composition (i. e. section 8. 3 smell: chemical reactions. Particular type of chemical reaction in which a substance combines with oxygen to form one or more oxygen containing compounds: reactants. Right of chemical reaction: must balance equations to avoid violation of the law of conservation of mass. Sections 8. 4: the coefficients in a chemical reaction specify the relative amounts in moles of each of the substances involved in the reaction, stoichiometry. The numerical relationships between chemical amounts in a balanced chemical equation: mass a moles of a moles of b mass of b. Limits the amount of product in a chemical reaction. Completely consumed in the reaction: reactant in excess.
