Why is it important to neutralize the reaction mixture during the workup? 1. It ensures that the ester is uncharged and therefor

e insoluble in water so that the product can be filtered. 2. If the reaction were not neutralized, the final product would not be in the desired oxidation state. 3. Neutralization prevents the ester from undergoing the reverse reaction to regenerate the carboxylic acid starting material. 4. Sulfuric acid is strong enough to dissolve glass and needs to be neutralized before the glassware loses its structural integrity.

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.

Describe how a homogeneous moisture differs from a heterogeneous mixture
Shalnov [3]

Answer:

Explanation:

Mixture: is combination of one or more substances mix together.

• The properties of the mixture are not same and contains the properties of all those component present in it.

• it is a combination of one or more Pure substances and can be separated by simple physical methods.

• it have varying boiling and melting point

Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.

The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.

Examples are:

• Salt water is mixture of water and NaCl and can be separated by physical mean.

• Air: mixture of gases

Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.

The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture

Examples is

• mixture of salt and sand

• mixture of water and sand

Liquid nitrogen is cold and can be used to cool objects to -196°C. If you put the bottle of warm air in liquid nitrogen at this
vampirchik [111]

Answer:

Explanation:

It depends on how this is done. If you raise the pressure, the nitrogen will disappear (liquify) and all that will be left will be the 21 % oxygen and the 1% argon.

The process is very complicated because the boiling point of nitrogen keeps on changing. The boiling point is unstable.
