A dilute electrolyte solution is prepared by dissloving iron(III) chloride in water. It is found to have a freezing point of of -2.10C. Estimate the Molarity of the solution
The simplest carbene known is methylene. The non-bonded electrons can be paired (singlet methylene) or unpaired (triplet methylene).
A balloon is filled to a volume of 9.00 multiplied by 102 mL at a temperature of 18.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 multiplied by 102 K. What is the final volume of the balloon?
What would be the pH of a 3x10-4 M solution of acetic acid (CH3COOH) given its acid dissociation constant Ka = 10-4.75? What are the concentrations of CH3COOH and CH3COO-
