Polarimetry, Spectroscopy, Pressure Measurement Three ways to measure a change in concentration Gas chromatography, mass spectrometry, titration Methods used to measure slow reactions with aliquots Zero Order Reaction rate of the reaction is independent of the concentration of the reactant Rate = k[A]⁰ = k First Order Reaction rate of the reaction is directly proportional to the concentration of the reactant Rate = k[A]¹ Unimolecular: A → products Second Order Reaction rate o...

Allows us to determine the molecule mass and the molecular formula of a compound, as well as some of it's structural featuresMass Spectrometry Tells us the kinds of functional groups a compound hasInfrared (IR) Spectroscopy Provides information about the carbon-hydrogen framework of an organic compoundNuclear magnetic resonance (NMR) spectroscopy A very small sample is placed in a mass spectrometer, where it is vaporized and then ionized (electron removed from each molecule). Electron ...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...
