Atomic mass: The mass of a single atom.
Bond formation exothermic concours fonction publique catégorie b et c 2018 H negative, bond cleavage endothermic H positive Standard enthalpy of vaporisation: The energy required to vaporise one mole of a liquid.
Forces, the higher the.p.Mechanism, SN2: A bimolecular process by which a halogenoalkane undergoes nucleophilic substitution.Undergo SN2 mechanism in nucleophilic substitution.Down Group 7, van der Waals forces increase as molar mass increases.p.Excess: The reactant which there is more of than needed to react with all of the limiting reagent.Table 24, standard Electrode Potentials: this is a very important table that is referred to a lot in exam questions.Halogenoalkane, tertiary: Halogenoalkanes that have three alkyl groups attached to the carbon atom bonded to the halogen.Stronger than dipole:dipole forces.Paulis exclusion principle: e- in single orbital must have opposite spin.If you need to extract information from the graph then make sure you use a ruler to get fairly accurate values for the binding energies of the relevant nuclei.Energy Definitions edit It should be noted that many of the energy definitions can be considered in the reverse direction with a corresponding change of sign for the energy.Water, ionic product of: The equilibrium constant for the dissociation of water into its ions, where H2O is taken to be constant.
Reactivity: A measure of the readiness of a substance to gain or lose.
In an ionic compound the and ions are attracted to each other by the electrostatic force between them, and build up into a strong lattice.
