Enzyme is a protein molecule that acts as the biological catalyst of chemical reaction where the substrates are converted into products. With the aids of enzyme, the rate of reaction will be increased since the enzyme provides an alternative pathway[...]read more
Na2CO3.x H2O is the formula for hydrated Sodium Carbonate, where x represents the number of water molecules present in the crystals. The first method I will use to determine x, will involve heating the crystals. When the crystals are heated,[...]read more
A. Introduction/Aims: The aim of the current investigation is to investigate the acid-catalysed Fischer esterification mechanism underlying the synthesis of the anaesthetic benzocaine using p-aminobenzoic acid and ethanol in excess. The resulting synthesised compound was subject to IR and melting[...]read more
Introduction The heat of combustion of alcohols is the change in kJ/mol when 1 mole of the alcohol is burnt in excess oxygen (O2). I will be investigating 6 alcohols, using predictions and a practical to guide me through this[...]read more
