When limestone (solid ) is heated, it decomposes into lime (solid ) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete — the lime absorbs from the air and turns back into hard, durable limestone. Suppose a limekiln of volume is pressurized with carbon dioxide gas to , and heated to . When the amount of has stopped changing, it is found that of have appeared. Calculate the pressure equilibrium constant this experiment suggests for the equilibrium between and at . Round your answer to significant digits. Note for advanced students: it's possible there was some error in this experiment, and the value it suggests for does not match the accepted value.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
