Document Summary
Stoichiometry: quantitative study of the composition of compounds and mixtures and other the amount of reactants or products involved in a chemical reaction. Compound: composed of two or more elements; has a fixed composition (every pure sample will always contain the same elements) Water is always 89% oxygen by mass and 11% hydrogen. Mixture: composed of two or more substances; has a variable composition. Water and ethanol can be mixed in any proportion. Atomic mass unit: convenient for expressing the mass of a single atom or molecule. 1/12 of the mas of one 12c; a single atom of 12c has a mass of 12 u. Average atomic mass: weighted average of the atomic masses of the various isotopes. Atomic number (z) = # protons in nucleus. N = m/m = mass (g)/molar mass(g/mol) Consecutive reactions: reactions that occur sequentially; products form one reaction are consumed as reactant in subsequent reaction. Able to ass the chemical equations together.
