In general ethers have a much lower boiling point than their isomeric alcohols. why?
Alex Ar [27]

Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .

Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.

Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.

Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .

Explain the purpose and function of a gene.
Kryger [21]

Function

Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.

Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.

Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.

Purpose

The purpose of genes is to store information.

Each gene contains the information required to build specific proteins needed in an organism.

Hope this helps !!

Explain what has to happen to join two monosaccharide units into a disaccharide.
yawa3891 [41]
Dehyrdration should happen to join two monosaccharide units into a dissacharide. It is used to build up molecules by losing some water moleculse in the process. In a dehydration synthesis reaction between two un-ionized monomers. Hope this answers the question. Have a nice day.

At constant pressure, density of gas is inversely proportional to its temperature. This is how hot air balloon is floating in ai
Arturiano [62]

Answer:

1.08 g/L is the density of air.

Explanation:

Pressure of the gas = P (atm)

Volume of the gas = V (L)

Moles of gas = n = \frac{w(g)}{M(g/mol)}

Temperature of the gas = T (K)

PV=nRt

PV=\frac{w}{M}\times RT

PM=\frac{w}{V}RT=DRT

where:

D = density of the gas = \frac{Mass}{Volume}

R = universal gas constant

w = Mass of the gas

M =Molar mass of the gas

Given = P = 1.0 atm , T = 54°C = 327.15 K

Average molar mass of the gas = 29 g/mol

Putting all the given values in above equation.

1 atm\times 29 g/mol=D\times 0.0821 atm L/mol K\times 327.15 K

D=\frac{1 atm\times 29 g/mol}{0.0821 atm L/mol K\times 327.15 K}

D = 1.08 g/L

1.08 g/L is the density of air.
