What’s the IUPAC name
hichkok12 [17]

Answer:

Methyl pentanoate.

Explanation:

Hello there!

In this case, according to the given information, we can see the correct structure will be:

                             O

                              ||

CH3CH2CH2CH2COCH3

Which matches with the structure of an ester due to the -COO- functional group. In such a case, the first part of the name is in function of the right side of the ester, in this case, methyl, followed by the left side, pentanoate, as it has five carbon atoms and is an ester (similar to an inorganic salt, but organic) and therefore, the name will be methyl pentanoate.

Regards!

State the aufbau principle.
Inessa05 [86]

Answer:

Explanation:

To show the sequence of electrons filling sublevels in an atom, the Aufbau's principle is one of the tenets that must be satisfied to write a proper notation.

  • Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies".
  • Note that based on this principle, we are not inferring that sublevels are filled in numerical order.
  • The patter of filling is shown below:

         1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f e.t.c

The article states that amplitude plays a role in what happens to a sound
Brums [2.3K]

Answer:

Sound waves travel through matter

Explanation:

Higher amplitude sound waves are more likely to be transmitted through matter instead of reflected. Lower amplitude sound waves are more likely to be reflected or absorbed, resulting in a lack of an echo. Sound can travel through air, water, and solids
