Calculate the ratio of the potential energies for the interaction of a water molecule with an Al3+ ion (of radius 53 pm) and with a Be2+ ion (of radius 27 pm).
Determine what amount of heat is required to increase the temperature of sixty grams of ethylene glycol from 15.1 degree Celsius to 40.3 degree Celsius?
Thermochemistry and Periodic Properties of Elements. State which atom is larger according to periodic trends. Explain the difference for each of the pairs.
An aqueous solution of CaCl2 has a vapor pressure of 83.0mmHg at 50 C . The vapor pressure of pure water at this temperature is 92.6mmHg .
A modern chealting agent used for this purpose is succimer (C4H6O4S2). Suppose you are trying to determine the appropriate dose for succimer treatment of lead poisoning.
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
Gold has a density of 19.3 g/cm3. How many pounds does a gold sphere weigh if it has a diameter of 5.20 inches?
An analyst was attempting to determine the percent KHP in an unknown sample. The analyst found the molarity of the standardized NaOH solution to be 0.1022 mol/L.
A 1.90 mole quantity of NOCl was initially in a 1.50 L reaction chamber at 400°C. After equilibrium was established, it was found that 36.0 percent of the NOCl had dissociated.
At 700 K the equilibrium constant for the reaction is Kp = 0.76. CCl4(g)-> C(s) + 2 Cl2(g) A flask is charged with 2.00 atm of CCl4, which then reaches equilibrium at 700 K. (a) What fraction of the CCl4 is converted into C and Cl2?
