|
|
RAM |
Average mass of isotopes of an element compared where 1 mol of c12 is 12g |
|
|
Mole |
Amount of substance containing the same number of entities as there are atoms in 12 g of carbon 12 |
|
|
Avogadro constant |
No. Particles per mole as 6.02 x 10^23 |
|
|
Molar gas volume |
Gas volume per mole at room temperature and pressure |
|
|
Molar mass |
Mass per mole of substance or sum of relative molecular masses or relative atomic masses of atoms in a substance |
|
|
Empirical formula |
Simplest whole number ratio of atoms of elements present in a compound |
|
|
Molecular formula |
Number and type of atoms of each element in a molecule in real quantities |
|
|
Hydrated |
Containing combined water molecules |
|
|
Water of crystallisation |
Water molecules that are bonded into crystalline structure of an ionic compound |
|
|
Concentration equation |
Mass/volume in g/dm^3 |
|
|
Ideal gas equation |
P v = nRT |
|
|
Strong and weak acids |
Strong acids completely dissociate releasing all the H+ ions into solution where as weak acids partially dissociate by only releasing a small proportion of the H+ ions into solutionMost organic acids are weak |
|
|
Oxidation number exceptions |
H in metal hydrides = -1 O in peroxides = -1 O to fluorine = +2 |
