Answer all questions
In today's experiment, benzoic acid and excess methanol are refluxed in the presence of a catalytic amount of sulfuric acid: + CH OH H.SO ? + H2O MW 136.15 Benzoic acid MW 122.12 Methanol density 0.791g/ml MW 32.04 1. Draw the structure for the expected organic product, shown as "?" in the equation above: 2. If the reactions starts with 10.00 g of benzoic acid and 25.0 ml. of methanol (excess), what is the theoretical yield of...

D. Addition of sulfuric acid to a flask of water is observed to increase the temperature of the flask. The creation of the mixture can be thought of as breaking interactions between water molecules (i.e., water - water interactions), breaking interactions between sulfuric acid molecules (i.e., sulfuric acid - sulfuric acid interactions) and forming new interactions between water and sulfuric acid (i.e., water - sulfuric acid interactions). Which of the following is true? Circle and explain your answer to receive...
