Explanation:
The dehydration product of oh in the presence of acid is Propene.
<h3>
Explain Propene and write its Chemical and Molecular formula?</h3>
Like ethene, propene (sometimes referred to as propylene) is a crucial building element for a variety of compounds, including the common polymer, poly (propene). But unlike ethene, propene is easily converted by substitution reactions into a variety of significant compounds. Propene is a colourless gas with a little aroma of petroleum.
Propene is an organic compound that belongs to the alkene family. It is a hydrocarbon with two carbon atoms and four hydrogen atoms. Propene's molecular structure is .
Propene is a hydrocarbon with the chemical formula . It is a gas at room temperature and pressure, but condenses to a liquid when pressurised or cooled.

(4) F2(g) is your answer, since gases have the highest entropy of all the three basic states of matter (yes, by this I am excluding plasma -_-)
Answer: 40cm^3
Explanation:
Since the The air today is approximately one-fifth oxygen, the approximate volume of oxygen in 200cm3 of air would be:
= 1/5 × 200
= 40cm
The answer is 40cm^3
