Assuming 100% dissociation, calculate the freezing point and boiling point of 1.83 m AgNO3(aq). Constants may be found here.
Picric acid is a monoprotic acid that has been used in the leather industry and in etching copper. However, its' laboratory use has been restricted because it dehydrates on standing and can become shock sensitive
A 45.0-L steel tank at 20.0°C contains acetylene gas, C2H2, at a pressure of 1.39 atm. Assuming ideal behavior, how many grams of acetylene are in the tank?
A solid mixture consists of 35.7 of KNO3 (potassium nitrate) and 6.3g of K2SO4 (potassium sulfate). The mixture is added to 130. of water. If the solution described in the introduction is cooled to 0
When 0.0200 mol gaseous NH3 and 0.0180 mol gaseous O2 are placed in a 1.00 L container at a certain temperature, the N2 concentration at equilibrium is 2.20Ã-10-3 M. Calculate Keq for the reaction at this temperature.
calculate Kc for the reaction below: 2P(g)+ 5Cl2(g) 2PCl5(g) The answer provided is 240. Why is that?
A solution of household bleach contains 5.25% sodium hypochlorite, NaOCl, by mass. Assuming that the density of bleach is the same as water, calculate the volume of household bleach that should be diluted with water to make 500.0 mL of a pH = 10.2..
usually some inception time is involved during the preparation of the Grignard. Explain the reason behind
human growth hormone in 25.0 mL of solution has an osmotic pressure of 0.109 torr at 25.0°C. What is the molar mass of human growth hormone?
Assuming the heat absorbed by the styrofoam is negligible, calculate the expected final temperature. The specific heat of water is 4.184 J g-1 K-1.
A gas at 225 K and 40 bar has a molar volume 26% larger than that calculated from the ideal gas law. (a) Calculate the compression factor Z for the gas under these conditions. (b) Which are dominating in this sample, the attractive or repulsive force..
Write the structures of the products you would expect to get if you react N-cinnamaldehyde-m-nitroaniline with catalytic hydrogenation (that means adding H2 and Pt or Pd).
The observed melting point of camphor is often low. Look up the molal freezing point depression constant K for camphor and calculate the expected depression of the melting point of a quantity
