Heating vents are usually placed on the floor because heat rises. If they weren't on the ground or near it then the house would not stay warm because all of the heat traveled up and out of the room!

Which of the following atoms would be expected to be diamagnetic in the ground state?
Rufina [12.5K]

The atoms that would be expected to be diamagnetic in the ground state is  magnesium

The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.

A paired electron is an electron that occurs in pairs in its orbital shell.

At their respective ground state, the electronic configuration of the given elements are as follows:

The electronic configuration of magnesium is 1s²2s²2p⁶3s².  As such its a diamagnetic atom.

The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.

The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.

The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.

Therefore, the atoms that are diamagnetic in the ground state is magnesium.

Four research teams measured the rotation period of a newly detected neutron star, and what each team wrote in its team notebook
makvit [3.9K]

Answer:

Explanation:

The correct measurement is .710 s which is equal to .71 s so second measurement that is 0.71 s is most accurate measurement .

B.  0.71s is the most accurate .

Precision depends upon measuring instrument . Measurement by highly precise instrument has greater precision .

The measurement of 0.75 ± 0.002s must have been taken from high precise instrument because it is capable of making measurement upto 3 decimal points .

Hence

C 0.75 ± 0.002s is most precise measurement .

State two conditions necessary for an esterification reaction to take place​
nadya68 [22]

Explanation:

Esterification occurs when a carboxylic acid reacts with an alcohol. This reaction can only occur in the presence of an acid catalyst and heat. It takes a lot of energy to remove the -OH from the carboxylic acid, so a catalyst and heat are needed to produce the necessary energy.
