The kinetics of the hydrolysis of the halogenoalkane RCH2Cl with aqueous sodium hydroxide
(where R is an alkyl group) was studied at 50 C. The following results were obtained:

Topic 1: Quantitative chemistry
Stoichiometry is the study of the relationship or ratios between the amounts of reactants and products in a
chemical reaction. Stoichiometric amounts or ratios are the amounts of reactant or product as given by the
TOPIC 6: KINETICS
6. 1 Rates of reaction
6.1.1 Define the term rate of reaction.
rate of reaction =
a decrease (or increase) in the concentration of a reactant (or product)
over a unit of time
There are different types of rates of reactions.
Topic 9: REDOX EQUILIBRIA
9. 1 Oxidation and reduction
Define oxidation and reduction in terms of electron loss and gain.
Deduce the oxidation number of an element in a compound.
State the names of compounds using oxidation numbers
VARIOUS ENTHALPY CHANGE DEFINITIONS
This page explains what an enthalpy change is, and then gives a definition and brief
comment for three of the various kinds of enthalpy change that you will come across.
You will find some more definitions on other page
TOPIC 4: BONDING
In this topic we will study the various interactions between particles (=bonding), and these are:
1. Ionic bonding
2. Covalent bonding
3. Intermolecular forces:
Van der Waals' forces
TOPIC 15: ENERGETICS (HL)
In this section we will study why some chemical reactions are spontaneous (or feasible) in terms of
energetics) and other reactions are not. The spontaneity or feasibility of a change (physical or chemical)
depends on the interac
IB TOPIC 14: Bonding
14. 1 Shapes of molecules.
14.1.1 Predict the shape and bond angles for species with five and six negative charge centres using the VSEPR theory.
You should be able to predict the electron distribution, molecular shape and bond angles
Topic 2: Atomic theory
2.1. The atom
2.1.1 State the position of protons, neutrons and electrons in the atom.
2.1.2 State the relative masses and relative charges of protons, neutrons and electrons.

Bohr returned to Denmark and resumed his role at the Copenhagen Institute. The
homecoming brought tears to many eyes, and a large celebration was planned to celebrate
his sixtieth birthday. Interest in atomic energy was inevitable and soon occ
Niels Henrik David Bohr was born on October 7, 1885, in a large Copenhagen house that
belonged to his maternal grandmother. His father, Professor Christian Bohr, was an

War and Personal Tragedy
Bohr watched the Nazis' rise to power with great unease, even as the rest of the world
dismissed them as ultimately harmless. In 1933 Hitler became chancellor of Germany, and
racial laws barring Jews from public posts were soon an
