Why does a cloudy mixture is seen after shaking a mixture of ethanol and coconut oil?
Because the oil does not dissolve in the ethanol, instead it becomes emulsified into tiny particles due to the shaking. The particles give the mixture a cloudy appearance.
Is it always possible to distinguish two substances from one another based on their appearance explain your answer using specific examples?
Generally is not possible; a chemical/physical analysis is needed. Examples: the appearance of sodium chloride and potassium chloride is similar, the appearance of ethanol and methanol is similar etc.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
- making a chemical analysis of the solution - using an adequate hydrometer for alcohol-water solutions
How many moles of ethanol C2H5OH are in a sample which weighs 39.2g?
Because the formula shows that each molecule of ethanol contains 2 atoms of carbon, 6* atoms of hydrogen, and 1 atom of oxygen, the gram molecular mass of one mole of ethanol is the sum of twice the gram atomic mass of carbon, 6 times the gram atomic mass of hydrogen, and the atomic mass of oxygen: 46.07. Therefore, 39.2 grams of ethanol constitutes 39.2/46.07 or 0.851 mole, to the justified number of significant digits… Read More
Is ethanol a mixture?
No. Ethanol is also alcohol. Ethanol is a compound. It is not a mixture.
What is the difference of absolute ethanol to the regular technical grade ethanol?
technical grade is bethween 96% and 98% ethanol and ethanol absolute means pure ethanol whithout water ('almost') 99.9% ethanol Absolute ethanol has no water whereas 96% ethanol has 4% water or 98% has 2% water. Thus, the reaction can occur with water.
Why does ethanol burn differently than ethanol and water mixed?
the main reason why ethanol burns differently then ethanol and water mix is mainly because when you add the water to the ethanol you are making the ethanol less potent so it will burn weaker.
Why 95 percent ethanol is used in laboratory?
So as not to 'waste' too much ethanol. To use 95 % ethanol allows some ethanol to be saved!
Why 70 percent ethanol is better than 100 percent ethanol for sterilisation?
bcz, 100% ethanol is more volatile when compared to 70% ethanol.... so that, the acting time of 70% ethanol is more and also 100% ethanol acts only on surface proteins whereas 70% ethanol acts on internal proteins.
Is ethanol a metal?
No, ethanol is an organic basic liquid, wine and beer contain ethanol, and it is flammable
Can you mix oil and ethanol?
Yes, we can mix oil and ethanol. This is because oil can dissolve in ethanol.
Why alkali metals not stored in ethanol?
Akali metals reduce ethanol to ethanoxides- they react with ethanol.
What happens when you put frozen ethanol into liquid ethanol?
That question is too vague. I'm assuming you mean a little frozen ethanol into a larger volume of liquid ethanol. This being the case, the ethanol will melt. That's it.
Why is ethanol treated with anhydrous?
Ethanol isn't "treated" with anhydrous. "Anhydrous" means "without water". Therefore, anhydrous ethanol simply means ethanol without any water molecules in it. It is normally 99.9% ethanol.
Is 70 percent ethanol the same with 70 percent ethanol?
Absolutely, recent painstaking scientific research has showed that 70% ethanol is the same as 70% ethanol.
What is the chemical formula for ethanol?
The chemical formula for ethanol is C2H5OH Can be empirically expressed as C2H6O Cheers to ethanol!
What is Ethanol use for?
ethanol fuel is use for gasoline if we didnt have ethanol there would be no cars or just no gasoline
What will happen to the boiling leaf when in ethanol what will happen to the leaf and the ethanol?
the ethanol will change colour and the leaf will soften
Is spirit an antiseptic?
The term "spirits" can refer to ethanol or beverages containing ethanol, and yes, ethanol is an antiseptic.
Is denatured alcohol and ethanol the same?
No. Denatured alcohol is ethanol with poisonous liquids to make the ethanol undrinkable.
Is ethanol silver nitrate a polar solvent?
Ethanol is a polar solvent. Ethanol will dissolve silver nitrate.
What is ethanol use in everyday life?
ethanol is used in everyday life as eating sugar which contains ethanol.
How is ethanol made?
Ethanol is made from sugar beets, sugar cane, corn, wheat, and barley. The sugar is extracted, microbes are introduced, ethanol is produced. That is how ethanol is made.
How is biomass converted to ethanol?
The biomass is changed into carbon dioxide and alcohol using yeast or bacteria to produce ethanol. The ethanol is processed to produce usable ethanol and byproducts.
