1. The same reaction takes place in two different vessels, which are initially at atmospheric pressure (1 atm). The first vessel is rigid and does not expand with change in pressure; the second vessel will expand to maintain a pressure of 1 atm inside. Over the course of a reaction, the second vessel expands by 1 liter. a) What is the amount of PV work done by the reaction for each of the vessels?b) Which vessel’s content has a higher enthalpy?c) ...

The amount of oxygen used by a house fly, at a steady temperature of 15°C, can be compared to its oxygen use at a steady temperature to 25°C. Knowing that increased temperature leads to increased biochemical reaction rates, and that flies are an incredible collection of biochemical reactions, you might reasonably predict that the rate of oxygen consumption by the flies is going to be higher at 25°C than it was at 15°C. In fact, the rate of increase for...

Grignard Reaction 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...
