Calculate the mean free path and the binary number of collisions per liter per second between HI molecules at 300 K and 1.00 atm. The collision diameter of the HI molecules may be taken to be 5.10 A. Assume ideal-gas behavior.
What is the concentration of each species present when equilibrium is reached? b. What is the value of Kc for this reaction at 500K?
How many grams of KCl would be required to react with 420 mL of 0.42 M AgNO3 solution?
An electron is confined to a one-dimensional box of length L. It falls from the second energy level to the ground state, and releases a photon with a wavelength of 322 nm. What is the length of the box?
Calculate the mass (g) of pure Na3AsO4 (s) and volume (mL) of 1.50 M HCl that are required to make 100.0 mL of a buffer solution at a pH of 6.80 and an H2AsO4-(aq) concentration of 0.100 M
Hydrogen fluoride behaves as a weak acid in solution. Two equilibria influence which fluorine containing species are present in solution.
A 33.5 mL sample of a KOH solution of unknown concentration requires 22.1 mL of 0.200 M solution to reach the end point in a titration. What is the molarity of the KOH solution?
The pressure on 200 ml of oxygen gas changes from 380 mm hg to 760 mm hg. The temperature does not change. What is the new volume of the oxygen gas?
explain why rutherford expected all alpha particles to go through the gold foil undisturbed.
What is the speed of an electron ejected from a metallic surface, where the metal work function is 2.06 eV and the radiation is at the following wavelengths
Calcium fluoride CaF2 is an insoluble salt. The Ksp is 3.4 x 10^-11. Calculate the molar solubility of calcium fluoride.
Explain the Reaction, If you treat an aldehyde wiith HCN you produce a cyanohydrin. For example
We performed this lab, but I'm having trouble taking the data collected and calculating the total concentration of both Ca2+ and Mg2+, along with the individual concentration of each.
