a-Calculate [OH-] of a 2.25×10^-1 M aqueous solution of hydroxylamine (HONH2, Kb = 1.1×10^-8).? part b-Calculate the pH of the above solution. pls show the step wise answer since i'm struggling with chem. (the full answer) to get the full rate:)
Assume that the estimates of the standard deviation for the mean mass of a series of three measurements, a serious of six measurements, and a series of nine measurements were identical.
What weight of A would be removed by four successive extractions with 25-mL portions of ligroin? How much ligroin would be required to remove 98.5% of A in a single extraction?
A 32.65-g sample of a solid is placed in a flask. Liquid toluene, in which the solid is insoluble, is added to the flask so that the total volume of solid and liquid together is 50.00 ml.
A steel container with a volume of 500.0 mL is evacuated, and 25.0 g of CaCO3 is added. The Container and contents are then heated to 1500 K, cuasing the CaCO3 to decomposed completely
