What proportions of benzene and ethylbenzene should be mixed (a) by mole fraction (b) by mass in order to achieve the greatest entropy of mixing
If you had a stoppered flask with basic luminol and then opened it to the air, why would the chemiluminescence be more pronounced than with the flask stoppered? Why is the chemiluminescence even more pronounced with the ferricyanide/hydrogen perox..
Write the lewis structure for SeF6. What is the general "ABX" structure, shape name, and molecular polarity?
When you go on the protein databank and look at the Ramachandran plot, it gives you 4 plots (general case, glycine, proline, and pre-proline).
The temoerature rose by 3.65C. Next, a small piece of calcium carbonate was placed in the same calorimeter and .100L of dilute HCl was poured over it.
What is the solubility of AgCl when it is in a solution of 0.15 M NaCl? (AgCl has Ksp = 1.8 x 10-10.) Make a reaction table. Include rows for initial concentration, change in concentration, and equilibrium concentration.
starting from alcohol that contains four or less carbon atoms and from benzene and toluene,
It takes 48.0J to raise the temperature of an 9.60g piece of unknown metal from 13.0c to 24.0. What is the specific heat for the metal? Express your answer numerically, in J/g.C
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
