Topic
1. Empirical formulae and calculating RAM from isotopes. Set: 20/09/2013 Due: 27/09/2013
Specification outcomes to be covered:
1) Calculate empirical and molecular formulae, using composition by mass and percentage compositions;
2) Explain the terms:
(i) empirical formula as the simplest whole number ratio of atoms of each element present in a compound,
(ii) molecular formula as the actual number of atoms of each element in a molecule;
3) Calculate the relative atomic mass of an element given the relative abundances of its isotopes;
2. Moles and solutions. Set: 27/09/2013 Due: 11/09/2013
1) Carry out calculations, using amount of substance in mol, involving:
(i) mass
(ii) gas volume
(iii) solution volume and concentration
3. Redox reactions Set: 20/11/13 Due: 6/12/2013
1) Explain what a redox reaction is, and how to calculate change in oxidation numbers, using 3 separate examples:
(i) Acid + metal
(ii) Group 7
(iii) (Group 2)
