5.2 Hess’s Law — A Level Chemistry Learning outcomes Candidates should be able to: apply Hess’s Law to construct simple energy cycles carry out calculations using cycles and relevant energy terms, including: determining enthalpy changes that cannot be found by direct experiment use of bond energy data Before you start You can’t set a match…
5.1 Enthalpy Change — A Level Chemistry Learning outcomes Candidates should be able to: understand that chemical reactions are accompanied by enthalpy changes and these changes can be exothermic (ΔH is negative) or endothermic (ΔH is positive) construct and interpret a reaction pathway diagram, in terms of the enthalpy change of the reaction and of…
Learning outcomes By the end of this topic, you should be able to: Analyse mass spectra in terms of m/e values and isotopic abundances (knowledge of the working of the mass spectrometer is not required). Calculate the relative atomic mass of an element given the relative abundances of its isotopes, or its mass spectrum. Deduce…
22.1 INFRARED SPECTROSCOPY Learning Outcomes Candidates should be able to: Analyse an infrared spectrum of a simple molecule to identify functional groups. 1 What Is Infrared Spectroscopy? In infrared (IR) spectroscopy, a sample is irradiated — exposed to radiation — with electromagnetic waves from the infrared region of the spectrum. The instrument used is a…
