6 0

Answer:

Option (D)

Explanation:

Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.

It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.

It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.

Thus, the correct answer is option (D).

Vlad [161]

Answer:

<h2>18 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

volume = final volume of water - initial volume of water

volume = 62 - 52 = 10 mL

From the question we have

density =  \frac{180}{10}  \\

We have the final answer as

<h3>18 g/mL</h3>

Hope this helps you

Why is an extraction a useful method of "pre-purification" of organic compounds? what physical properties does the process rely
ASHA 777 [7]

Explanation :

Extraction : It is a separation technique in which one compound is separated from a mixture of compounds.

In  a chemical process, the solution may not contain only the desired product but there maybe a mixture of products present.

So, for obtaining the desired product we need to get rid of the other products in a mixture like catalyst (if used), other by products or unreacted starting material.

For a compound to be extracted it has to be soluble in the extracting solvent.

Therefore, this process is based on the miscibility of solute and solvent in a mixture.
