Atom does not need any electrons if it has a completely filled outermost shell.
Answer: the correct option is 1 (It ensures that the ester is uncharged and therefore insoluble in water so that the product can be filtered.)
Explanation:
Esters are formed through a process known as esterification. This involves the heating of a carboxylic acid with an alcohol while the water formed is continuously removed. In order for the reaction to occur at a maximum rate, an acidic catalyst is used. The most common acid catalysts includes:
- hydrochloric acid and
-sulfuric acid.
These catalyst needs to be neutralized in order to isolate the product. This is so because the solution begins to precipitate when the reaction mixture is neutralized.
Thus it is important neutralize the moisture in order to filter out the ester from the mixture, which otherwise will be in a dissolved state and will not be recoverable.
Answer:
You can tell by looking at the reaction. If it stops bubbling or steaming it is finished. It s going to react and start bubbling. When it stops bubbling and fizzing, the reaction will be over.
the answer is C because convalent bond is being bonded to an anion
Answer:
Miles (mi) or kilometers (km)
Explanation:
This is a big distance and it needs to be measured using a large unit of measurement, unlike feet, yards, or meters.
