If one were to perform carbon dating on living clams instead of getting a zero age ( they are in fact living) one would get an age of approximately 400 years old for these living clams. This is called the reservoir effect, and must be taken into account when using carbon dating, how does the reservoir effect arise? Hint: consider what event "starts the clock" of carbon-14-dating
The molality of the solution is determined to be .0480m. What is the molar mass of the substance?
(i) Is the system in equilibrium? If not, which direction must the reaction proceed for equilibrium to be established? (ii) What is the Kp for this system at equilibrium?

A 93.7 g (5.20 mole) sample of water is heated to exactly 94.4 celsius. It is then added to 90.1 g (5.00 mole) of water at 22.5 celsius in a styrofoam cup calorimeter.
An experimenter finds that she is unable to establish a premixed carbon monoxide flame when using an oxidizer composed of high-purity O2 (21%) and high-purity N2 (79%)
A tire has a pressure of 780 mmHg at 27°C. If the tire is heated to 47°C on hot pavement, what the new pressure will be:
The Cu-Ni system is an isomorphous one, meaning that the crystal structure does not change with alloying; in particular, Cu and Ni atoms randomly substitute for one another within a FCC crystal structure
