Document Summary
Intensive property: values do not change with different amount of sample (eg. temperature) Extensive property: values that change depending on amount of sample (eg. volume) Absolute zero at 0k: -237. 15 degrees celsius. Recall (aka you should know: si units, nomenclature, balancing equations. Law of mass conservation: mass of reaction is conserved. Law of definite proportions: pure substance has same ratio of elements. Law of multiple proportions: elements make compounds with mass ratios of whole number multiples (no oxygen in an element) Empirical formula: simplest whole number ratio. where h is planck s constant (will be given) Binding energy is amount of energy that must be given to particle to shoot it out of its orbit. Kinetic energy of the left over energy after particle has left orbit. Quantum numbers n: row of periodic table (1, 2, 3) l: spdf orbital (0, 1, 2) M: magnetic number (0, 1, 2)
