Post predictions, help each other etc..
Do you know what practicals could come up on the inorganic paper or organic paper? Or is it possible they could all be spread over the two papers? :s
1.Make up a volumetric solution and carry out a simple acid–base titration
2.Measurement of an enthalpy change
3.Investigation of how the rate of a reaction changes with temperature
4.Carry out simple test-tube reactions to identify anions and cations.
For the second paper:
1.Distillation of a product from a reaction
2.Tests for alcohol, aldehyde, alkene and carboxylic acid
What does the 'n' in the Ideal Gas Equation actually mean?Say if we had a question asking us about the decomposition of Potassium Carbonate upon heating, what would the 'n' mean? Moles of oxygen or Potassium Carbonate?
Moles of potassium carbonate because the oxygen is in excess.
