System A undergoes an increase in entropy while system B undergoes a decrease in entropy.

Entropy is the degree of disorderliness of a system. The entropy of a system depends on the number of particles present in the system as well as the state of matter.

Entropy is increased when solid particles dissolve in water because more particles are produced thereby increasing the level of disorderliness in the system.

On the other hand, when vapor is condensed, the degree of disorderliness decreases as gases are converted to liquids.

The 1h nmr spectra corresponds to an alcohol with the molecular formula c5h12o. Deduce the structure from the spectra.

Sav [38]

Answer:

The question is incomplete. The spectra can be seen in the first picture in the attachment.

The molecule corresponds to the tert-amyl alcohol.

Explanation:

From the molecular formula, we can calculate the double bond equivalent, to know if there is any unsaturation in the molecule. For a compound of molecular formula CxHyOzXqNp

$DBE= (2x+2)- (y+q-p) ÷ 2$

DBE= (2.2+2)-12 ÷12 = 0

Therefore, the molecule does not have any unsaturation.

Considering the chemical shift values and the multiplicity, the structure that satisfies the spectra corresponds to the tert-amyl alcohol (structure in attachment).

Using only the groups of the periodic table, choose one element that is chemically similar to each of the following elements.

zhenek [66]

Elements that are in the same columns (vertical) are chemically similar.

Carbon- Si
Cesium- Na
Krypton- Ar
Magnesium- Ca
Al- try Boron
Br try Cl

These are just the ones I picked but it could be any in the same column
