Abstraction: The aim of this experiment is to expeditiously execute a fischer esterification of 1-Hexanol to organize H2O and hexyl ethanoate. and to corroborate the esterification with a atomic magnetic resonance ( NMR ) spectrometry. It was found that 0. 3963 grams hexyl ethanoate was formed with a percent output of 33. 2 % ….

Aim: To investigate the effect of different concentrations of a heavy metal chloride, namely lead chloride, on the growth of cress seeds.
