WebDistillation is a common practical completed in organic chemistry. Distillation is used as there are times that a reaction does not go to completion or there are other chemicals produced as well as the desired product. Distillation allows you to separate compounds by their boiling point. Chemicals with the lowest boiling point will distill first.

WebCH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l) Step 2: Combustion reactions are always exothermic (Δ H is negative) so the reactants should be drawn higher in energy than the products. Step 3: Draw the curve in the energy level diagram. Step 4: Draw arrows to show the Ea and ΔH including their values. WebInfrared (IR) spectroscopy is a technique used to identify compounds based on changes in vibrations of atoms when they absorb IR of certain frequencies. A spectrophotometer irradiates the sample with IR radiation and then detects the intensity of IR radiation absorbed by the molecule. Symmetrical molecules such as O 2 or H 2, are therefore IR ...
