Why is the catalyst Copper Chloride faster at the decomposition of hydrogen peroxide than Postassium Iodide and Lead Oxide
We are supposed to prepare a probable scheme to separate a mixture of 3 components: the first will be an acid (or base) organic compound, the second will be a neutral organic compound, and the third will be 1,4-dibromobenzene. I know how to separate the acid (or base) component. However, the remaining 2 neutral compounds in the dichloromethane solution I'm not sure how to deal with. For most of them, I know I can use fractional distillation, as their melting/boiling points are very different, but there is one possibility of the 1,4-dibromobenzene with benzil and the melting points are so close to each other that the fractional distillation may not be possible. Is there another way to separate and purify these? Please no copy/paste responses - they will not get the ratings. I need to know exactly how (and why).
Discuss the general procedure on how solvents affect the rate of alkyl chloride hydrolysis. Include the data that need to be collected
1.628 G Sample Of A Hydrate Of Magnesium Iodide Is Heated Until Its Mass Is Reduced To 1.072 G And All Water Has Been Removed. What Is The Formula Of The Hydrate?
What is the pressure in a 65.0L cylinder filled with 0.235 moles of nitrogen gas at a temperature of 105K.
A 0.4780-g sample of impure Ca(OH)2 is dissolved in enough water to make 57.00 mL of solution. 20.00 mL of the resulting solution is then titrated with 0.1140-M HCl.
For each solution, determine the number of moles of HAn and of An- ion at equilibrium. For each solution, caluate the HAn and An- ion molar equilibrium concentrations. Determine the reciprocal of the An- ion concentration for each solution.
