Airida [17]3 years ago

Answer: Option (B) is the correct answer.

Explanation:

A process in which liquid mixture is separated by selective boiling and condensation is known as distillation process.

It is known that boiling point of alcohols is low therefore, when a mixture of alcohol and water is boiled then alcohol will evaporate from the mixture and the water will remain as the liquid.

Therefore, the distillation column will collect the vapors of alcohol separately and hence, it can be separated from water.

Thus, we can conclude that distillation is an effective method for separating a mixture of alcohol and water.

<span>The  effective method for separating a mixture of alcohol and water is the
Distillation
</span> By this you only get about 70% alcohol 30% water
As  they are  <span>azeotropes and cannot be distilled further
so correct option is B

A medium that works by showing two reaction types is called a differential medium

<h3>Differential media</h3>

Differentia media are one of the numerous culture media used in culturing microorganisms. They are also known as indicator media.

They are called differential media because they are able to make a distinction between two microorganisms growing on them based on the biochemical characteristics of some organisms in the presence of certain indicators or nutrients.

A 15.9 g sample of sodium Carbonate is added to a solution of acetic acid weighing 20 g. the 2 substances react, releasing carbo
adell [148]

Answer:

hope that helps

Explanation:

The total mass of reactants taken = 15.9 + 20.0 = 35.9 gm. From the conservation of mass the final mass of the contents of the vessel should also be 35.9 gm. But it is only 29.3 gm. The difference is due to the mass of released carbon dioxide gas.Hence the mass of carbon dioxide gas released = 35.9 – 29.3 = 6.6 gm

Carbon dioxide (CO2) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 30 lbf/in2, and a volume of 1.6 f
solong [7]

Answer:

The answer to this question can be given as:  

The initial pressure P= 30 lbf/in2

The initial temperature T1=80°F.

The initial volume=final volume V= 1.6 ft3.

Final  temperature T2=500°F

Heat transfer Q=-2.6 Btu.

pressure (P) (lbf/in2) change into lbf/ft2

P=30 lbf/in2=4320lbf/ft2.

Temperature (T1) °F change into °K

temperature T1=80°F=539.67 °K

Ideal gas formula:

M=PV/RT1.                   where T1=initial temperature.

M=4320*1.6/35.114*539.67.

M=0.364749 lb             Mass at Carbon dioxide (CO2).

DQ=DU+W            second law.

-2.6=MCV(T2-T1)+ W        

-2.6-(0.364749*1.6(500-80))=W

W=-27.111 b+u  am----> work done.

Explanation:

The explanation to this question can be given as:

Firstly we write the equation that is given in the question like, pressure, volume, gas constant, temperature. Then we covert the pressure and temperature into there possible values. Then We apply the formula of Ideal gas that is  M=PV/RT1. where M is  the mass, P is the pressure , V is the volume , R is the gas constant (0.08206 L·atm·K−1·mol−1)  and T1 is the initial temperature. Then we use the second formula that is DQ=DU+W. Where DQ= Heat transfer, DU=MCV(T2-T1)and W= work. It is used for finding work.

Calcium bicarbonate (Ca(HCO3)2) Ca:H:C:O = 1:2:2 ___ Lithium sulfide (Li:2s) Li:S = 2:__
Anastaziya [24]

Answer: The ratio of atoms in calcium bicarbonate ; Ca : H : C : O = 1:2:2:6.

The ratio of atoms in lithium sulfide; Li : S = 2 : 1

Explanation:

In calcium bicarbonate:Ca(HCO_3)_2

In a molecular formula of calcium carbonate there are:

Number of Calcium atoms = 1

Number of Hydrogen atom = 1 × 2 = 2

Number of Carbon atoms = 1 × 2 = 2

Number of Oxygen atoms = 3 × 2 = 6

So, Ca : H : C : O = 1 : 2 : 2 : 6

In lithium sulfide :Li_2S

In a molecular formula of lithium sulfide there are:

Number of Lithium atoms =  1 × 2 = 2

Number of Sulfur atoms = 1

So, the Li : S = 2 : 1
