If 1.00 \rm mol of argon is placed in a 0.500-\rm L container at 20.0\, ^{\circ}C, what is the difference between the ideal pressure (as predicted by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)?
For argon, a = 1.345 \;\rm (L^2\cdot atm)/mol^2 and b = 0.03219\; \rm L/mol.
cyclohexane-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the first 1 mL fraction look different from that of the last 1 mL fraction?
Calculate the cell potential for the following reaction as written at 53C, given that [Zn2+]= .841M and [Fe2+]= .0160M. Standard reduction potentials are Zn(s)= -.76, Fe2+(aq)= +.771, Zn2+(aq)= -.76, Fe(s)= -.04
In the preparation of the esters given in this experiment, the reaction product was extracted with 5% sodium bicarbonate solution in the isolation step. Why? What gas was evolved during this washing step? Write a balanced equation for the reaction..
When a sample of aqueous hydrochloric acid was neutralized with aqueous sodium hydroxide in a calorimeter, the temperature of 100.0 g of water surrounding the reaction increased from 25.0°C to 31.5°C.
Radio station KLBJ broadcasts at a frequency of 93.7 × 106 s-1. Determine the length of the waves that corresponds to this frequency.
Ozone (O3) is produced in the laboratory from oxygen (O2) by means of an electric discharge. Once generated, ozone gradually decomposes into oxygen by first-order kinetics. The following data were obtained from a sample of freshly prepared ozone
Identify the limiting reagent and the volume of CO2 formed when 11L CS2 reacts with 18L O2 to produce CO2 gas and SO2 gas at STP.
Write a detailed mechanism for this reaction that accounts for the net retention of detailed mechanism for this reaction that accounts for the net retention of configuration when Ag+ and a low concentration of hydroxide are used.
Write the balanced net ionic equation for the following reaction in basic solution. Be sure to show phase labels in your final answer
In a titration of HNO3, you add a few drops of phenolphthalein indicator to 50.00 mL of acid in a flask. You quickly add 26.50 mL of 0.0502 M NaOH but overshoot the end point, and the solution turns deep pink.
It takes 49.0 J to raise the temperature of an 11.7 g piece of unknown metal from 13.0 C to 24.0 C. What is the specific heat for the metal?
Calculate the percent manganese in the sample as Mn3O4 (only part or none of the manganese may exist in this form, but we can make the calculations on the assumption that it does)
