properties of matter that depend on the quantity of the matter observed (volume, mass, heat).
properties of matter that are independent of the amount of matter observed (density, temperature).
uniform throughout and include such things as solutions
not uniform; components of the mixture vary in concentration throughout the mixture.
subjective properties (colour, Odour, etc.)
Objective and empirical properties (weight, volume, etc.)
the degree of reproducibility of a measured quantity.
how close a measured value is to the actual value.
elements with the same number of protons but a different number of neutrons and a different atomic mass.
or (Z) is the number of protons in the nucleus of an atom. Atomic number is not the number of electrons in an atom, however, in an electronically neutral atom the number of electrons and protons happens to be the same.
(fractional abundance of isotope 1)(mass of isotope 1)+ (fractional abundance of isotope 2)(mass of isotope 2) + . . . + (fractional abundance of isotope n)(mass of isotope n)
number of elementary entities in a mole, 6.02x10^23 mol^-1
the calculated quantity of product that one expects from given quantities of reactants.
molecular compounds that are almost completely ionized in water.
one that is completely ionized in an aqueous solution.
one that is incompletely ionized in aqueous solution.
loss of electrons by a chemical spieces [Oil--> Oxidation is Losing]
gain of electrons by a chemical spieces [Rig--> Reduction is gaining]
causes a chemical species to lose electrons and get oxidized in the process.
causes a chemical species to gain electrons and get reduced in the process.
