Diffusion is the net movement from an area of higher concentration to an area of lower concentration. The mechanism by which this happens is the random molecular motion: the right answer is " <span>Diffusion is
the movement of molecules from an area of lower concentration to one of
higher concentration by random molecular motion"</span>
Explanation:
The purpose of this seven-page lab report is to use simple and fractional distillation to purify volatile liquids. The boiling points were obtained from the distillate collected drops and the efficiency of the two methods of purification were compared. The introduction experiment, data, conclusion
Use the D = M/V equation, in which Density can be found by dividing <em>Mass/Volume</em>.
To solve, first find a rectangular prism tub that is filled to a certain level. Next, place the rock inside to find the amount of displacement (or how high the water level goes up.) In this way, you can find the <em>volume of the rock</em>.
Next, solve for the Mass. This can be found by dividing the total weight from the gravitational pull. This would give you the mass.
Finally, to find Density, divide the Mass found with the Volume. This would give you your final answer

Answer:
To synthesize cis-2-methylcyclopentyl from methycyclopentanol, you need to replace the acetate hydroxyl group with acetate by inverting the configuration.
Explanation:
To understand the process, you need to understand the nucleophilic mechanism taking place in the process. This is the first stage of the process. Hydroxide is a poor leaving group, to it must be converted to a good leaving group. To effect the change, it is necessary to use p-toluenesuphate.
p-toluenesuphate is favored because this can be prepared by a reaction that alters none of the bonds attached to the stereogenic center.
The reaction of p-toluensulfonate with potassium acetate in acetic acid effects the conversion to give the final product: cis-2-methylcyclopentyl.
