Highly toxic disulfur decaflouride gas decomposes through a radical reaction to reversily form sulfur tetraflouride and sulfur hexafluoride gases. A 2.00L flask originally containing 0.500M disulfur decaflouride is allowed to reach equilibrium and found to contain 0.023M disulfur decaflouride. If an additional 0.125mol of the disulfur decaflouride is added and equilibrium re-established, what will be the concentrations of each component
calculate the molar absorptivity (epslion) of Cu2+ at 620nm given that the curvettes used in lab had a pathlegth of 1.00 cm.
A solution is 0.0100 M in Pb2+ ions. If 0.103 mol of solid Na2SO4 is added to 1.00L of this solution (with negligible volume change), what percent of the Pb2+ ions remain in solution.
determine the freezing point of this solution If 18.0 grams of a nonelectrolyte that has molar mass = 44.2 g/mol are combined with 110.0 grams of the solvent,?
