Answer:
The correct answer is: <u><em>"The ethanol will evaporate first"</em></u>
Explanation:
Fractional distillation is a physical process used to separate various liquid mixtures in which liquids have nearby boiling points. In other words, both compounds are volatile (volatility is the property of evaporating, moving from the liquid to the gaseous state).
The process consists in heating the liquid mixture to be separated. Upon reaching the boiling temperature of the most volatile component (with a lower boiling point) a vapor phase will be formed, which will mostly contain this substance at the beginning.
Then, as the temperature continues to rise and as time goes by, multiple evaporation and condensation cycles continuously occur (each cycle is known as the "theoretical plate"), until the lower boiling constituent first emerges, that is, It will separate.
In this case, since ethanol is the element with the lowest boiling point, it will be the most volatile and will separate first. So <u><em>the correct answer is: "The ethanol will evaporate first"</em></u>
Answer:
The biodegradability of soap moleculea means the soap molecules are degradable in nature it doesn't causes water pollution as comparing as detergent.....
According to Boyle's Law,
" the volume of a fixed mass of gas is inversely proportional to the pressure applied on it'.
Mathmatically,
V ∞ 1 / P
Or,
V = k / P
Explanation:
The balloon filled with Neon gas outside the chamber will have greater volume than in the chamber because the pressure in the chamber is high as compared to outside. So, the outside force brings the molecule of gas to get closer to each other.
They are called inert gases, Nobel gases.
The common character in them all that they have a complete last electron shell. That they rarely tend to form any further chemical compounds.
