Explain how much heat is absorbed when 1 mol CS2 (g) produces from its elements at these conditions?
When 1 mol CS2 (l) forms its elements at 1atm and 25degrees Celsius, 87.9 kj is absorbed, and it takes 27.7kj to vaporize 1 mol of the liquid.
Determine the pH required in an aqueous solution in order to reduce the solubility of Mg(OH)2 to 2.0x10-6M.
Ksp = 1.5x10-11 for Mg (OH)2
