Unit 4B: Making Nail Vanish Remover Introduction In the manufacture of ethyl ethanoate, there are a few techniques used, one of them being reflux. The principle behind using reflux is that it boils the reactants without losing any product or reactant, especially through vapour or gas. In the reaction there is a round bottom flask containing the reactants and a condenser with a water inlet and output. Due to organic chemicals being inherently unstable, when heated they will evaporate, res...

HESI A2 Biology Study Guide 2023 Cellular respiration is the process inside of cells that converts nutrients (such as sugars, amino acids, and fatty acids) into ATP (adenosine triphosphate), which is used throughout the organism for energy. Large molecules are broken into smaller molecules, which releases both energy and waste. Aerobic respiration occurs in the presence of Oxygen and has four main stages:  Glycolysis: Larger sugar molecule is broken down into 2 smaller sugar molecules in...
