In Chemistry for A-Level exams, whether for H1, H2 or H3 syllabus, students are allowed to refer to a Chemistry data booklet, except for SPA exams.
Do you know that the booklet itself is able to help move you to your distinction closer?
In this JC Chem data booklet, a long list of chemical data are given. Let us illustrate some of the uses of this booklet to secure your distinction! (More will be revealed in our Chemistry group tuition class)
Chemistry Data Booklet – Important Constant Values
For the Avogadro constant, be prepared to perform calculations, including use of the mole concept, to determine masses, volumes of gases (e.g. in the burning of hydrocarbons) and also volumes and concentrations of solutions. This portion of the Chem data booklet has other values such as the Mole, the Faraday and Planck constants.
Data on ionisation energies of the selected elements in the Periodic Table are given as well, along with their proton numbers. Also, bond energies of diatomic and polyatomic molecules are given as well.
With these info in the booklet for Chemistry, be prepared to apply Hess’ Law to carry out calculations involving given simple energy cycles.
A list of the standard electrode potential and redox potentials, [E at 298 K (25 °C)], are provided as well, in both alphabetical and decreasing order of oxidising power. The requirement here is that JC Chemistry must be able construct redox equations using the relevant half-equations.
Other info set are the atomic and ionic radii, the characteristic values for infra-red absorption, and the typical proton chemical shift values are provided in full as well. The use will be illustrated in our tutorial lessons.
The key idea here is to know ahead, what each set of data is for. What we do not wish to see is students going into the exam hall, when not knowing what to do, simply stare at the data booklet. This won’t help!
Put another way, the data booklet for Chemistry is here to help. Use it fully!
(If you wish to obtain a copy of the booklet for your Chem revision, download it under either H1 Syllabus or H2 Syllabus.)
