Overview
Heat of Formation of Magnesium Oxide
Chemistry
To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law, which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction Chemical reactions require heat energy to complete, called an endothermic reaction, or produce heat energy, and thus called an exothermic reaction. The heat…

Synthesis of Acetophenetidin by Amide Synthesis
Chemistry
The objective of this experiment is to compare the products of amide synthesis and Williamson Ether Synthesis, and determine if one synthetic route is more favorable than the other. In Part 1, we attempted to synthesize acteophenetidin crystals using amide synthesis. To begin, we eliminated the colored impurities from the p-Phenetidine (reddish-brown) by adding 2g…
