Making Copper Sulphate from Copper Oxide
(preparing a salt from two soluble reactants)
This process also works the same in reverse.
a gas atmospheric pressure)
A GAS SYRINGE is used to collect gases during reactions to allow molar gas calculations to be performed
N2 + 3 H2 ⇌ 2 NH3

Temperature and the Haber process
Ethanol can be produced in two main ways:
1. Fermentation – sugars are turned into ethanol and carbon dioxide through the anaerobic respiration of YEAST.
2. Hydration of Ethene (crude oil fraction) – reacting ethene with steam in the presence of a catalyst (addition reaction)
A HOMOLOGOUS series is a series of compounds that have the same general formula and similar chemical properties but have variation in boiling points.
