Textbook Question
Chapter 5.3, Problem 28P

Calcium carbonate, CaCO 3 , has two common crystalline forms, calcite and aragonite. Thermodynamic data for these phases can be found at the back of this book.

(a) Which is stable at earth’s surface, calcite or aragonite?

(b) Calculate the pressure (still at room temperature) at which the other phase should become stable.

Solve the following problem. Round off the final answer to three decimal places. A popular web site state that a 200 pound person will burn 450 calories/hour bicycling (moderate effort) and 650 calories/hour rock climbing (ascending). A 150 pound person decides to start a training routine in which she will bicycle for 45 minutes, 3 times a week and rock climb for 1.50 hours every weekend. How many calories will she have burned after 8 weeks of training (assuming she consumes at the same rate)?
