Assuming that the smallest measurable wavelength in an experiment is 0.410 fm (femtometers), what is the maximum mass of an object traveling at 549 m·s-1 for which the de Broglie wavelength is observable?
calculate the final temperature of the gas mixture. Assume the heat capacities of the gases are constant and are given in Appendix B of your text.
which portion of the titration curve are you in to reach pH = 7? Show your calculations to prove that dilution of 10,000 gal aniline requires 0.58 gal of this acid.
Now if your lab partner needed 7.030 x 1019 molecules of Sodium cyanide (NaCN), how many milligrams would you need to weigh out?
In a voltaic cell, the anode is negative relative to the cathode. Oxidation occurs at the anode of either type of cell (voltaic and electrolytic).
Give explanation for arrangements how you decide the boiling points comparison - Arrange all these compounds in order of increasing boiling points
An aqueous solution is 22.0% by mass silver nitrate, AgNO3, and has a density of 1.22 g/mL. What is the molarity of silver nitrate in the solution?
An iron (II) complex of the formula FeL5 2+ might have either square pyramidal or trigonal bipyramidal geometry. Would it be possible to differentiate between these geometries on the basis of a magnetic susceptibility? How would the number of unpa..
A beaker with 160 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.40 mL of a 0.400 it M HCl solution to the beaker. How much will the..
How would this computed ? compare with the dimensions of a typical atom? (-1 if much smaller, 0 if about the same magnitude, +1 if much bigger)
Consider the reaction: 2 K(s) + 2 H2O(l) -> 2 KOH(aq) + H2(g), DH = ? The heat released when 24.9g of K reacts with excess water is 124 kJ. Determine the enthalpy change, DH, for the above equation as written
grams of a sulfate-containing unknown with excess barium chloride. If 0.6500 grams of barium sulfate is produced, what is the percentage sulfate in the unknown?
