Diazomethane, CH2N2, is used in the organic chemistry laboratory despite its danger because it produces very high yields and is
dexar [7]

Answer:

See picture below

Explanation:

You are not providing the starting compound. However, I found a similar question so, I will draw the product of this compound, and then, you follow the same procedure.

As the problem states, the diazomethane is often used in reaction with carboxilic acid. This kind of reaction will do an esterification reaction, and the final product will always result in an esther.

So, with the example I give you here, all you have to do is replace the OH in the carboxilic group of your initial compound, for the OCH₃ group.

See picture below.

Hope this helps

Veronica is taking an average of 16 height measurements in a brand-new experiment. Which term is this the best example of?
Varvara68 [4.7K]

Answer:

Repetition

Explanation:

The best term to describe this example is repetition and not replication.

Most times, to obtain an accurate and precise reading which is reliable, scientist makes several repeated measurements. The average gives the most reliable representation of the phenomenon being tested.

This process is called repetition.

On the other hand, duplicating an experiment is replication. Experiments are replicated to proof their validity.

  • Since this is a brand new experiment where 16 height measurements are reported, we are dealing with a repetition situation.

To dilute a HCl solution from 0.400 M to 0.100 M the final volume must be
sp2606 [1]

<u>Answer:</u>

<em>The final volume must be 400 mL.</em>

<em></em>

<u>Explanation:</u>

Let us assume the Initial volume as 100ml

Using dilution factor formula  

\\$M_{1} \times V_{1}=M_{2} \times V_{2}$\\\\$0.400 M \times 100 m l=0.100 M \times V_{2}$

So,

$V_{2}=\frac{0.400 M \times 100 m l}{0.100 M}=400 m l$

Thus, the final volume must be 400 mL.
