In the dehydration experiment, several ml of saturated sodium chloride is used to transfer crude product after the initial distillation. Why is saturated sodium chloride, rather than pure water, used for this experiment.
two mwthods were described for determining the volume of the flask used for the molar mass determination.
calculate the maximum number of moles, liters and grams of H2S that can form when 187 g lead sulfide reacts with 140. g water at 29.0 °C and 0.75 atm of pressure.
Describes the six possible ratios are in the reaction. Include the formula of the species in the relationship.
Using curved arrows, show how the species in part (a) can act as Lewis bases in their reactions with HCl, and how the species in part (b) can act as Lewis acids
A 35.0 mL sample of 0.150 M acetic acid (CH3COOH) is titrated with 0.150 M NaOH solution. Calculate the pH after the following volumes of base have been added.
Compound A is unchanged when treated with dilute base, but treatment of A with concentrated NaOH and heat gives a new compound B (C10H19N) that decolorizes Br2 in CCl4. Compound B is identical to the product obtained from the reaction sequence bel..
Consider following cell. SCE stands for the saturated calomel reference electrode, which has a fixed potential of 0.244 volt. Pt|VOSO4 (0.0824 M), V2(SO4)3 (0.395 M), HClO4 (0.0100 M) || SCE Calculate the cell potential.
Draw the major monoalkylation product(s) you would expect to obtain from reaction of benzoic acid with chloromethane and AlCl3. If there is more than one product draw all in the same window.
For each reaction, identify the acid-base conjugate pairs. Then rank all reacionts in order of increasing tendency for the reaction to go to completion (to the right)
