Discussion
Temperature units use the Celsius scale and the Kelvin scale. Describe both scales and discuss the differences between the two and the conversion process. What would be the boiling point of water at 1 atmosphere? Explain how you arrived at the answer? Show the process you used.
What is the heat energy required to convert 0.261 moles gaseous ethanol at 300 deg.c to 25 deg.c at 1 atm with the following information.
How large should n be in order to approximate the integral from 0 to 1 sin(X^2) dx accurate to with in .001 using the midpoint rule (please show how to find the K value also)
Explain how many milliliters of a stock HCL solution labeled specific gravity 1.19 as well as assay 38% will be needed to prepare 2L of a 1.5N HCL solution
Have you ever wondered about how a frost-free refrigerator remains, well, frost-free? The key is sublimation During certain times, the freezer compartment is warmed slightly
As mentioned before, our asteroid is in the shape of a sphere and has a mass of 1000 kilograms. Determine the density (in grams per cubic centimeter) of this asteroid if its diameter is known to be 1.2 meters. Useful information: 1 kg = 1000 g, 1 m =..

The average water loss during a triathlon is 1.40 L in one hour. The average time to finish a triathlon is 12.6 hours. How much sweat is lost in m^3?
Show, with the aid of a form of the Nernst equation that when using a pH sensitive glass electrode and reference electrode that the measured potential is proportional to pH.
A student was given a solid for an unknown. Its melting point range was 119-121 degrees Celsius. The student has previously worked with benzoic acid, and has observed that it was a white crystalline solid with a melting point of 122 degree Celsius..
The broad feature of the spectrum are therefore expected to be hydrogen-like, the differences arising largely from the mass differences. Predict the wavenumbers of the first three lines of the Blamer series of positronium. What is the binding ener..
