show transcribed data consider two organic molecules, ethanol and benzene. one dissolves in water and the other does not. why? t
aalyn [17]

Benzene lacks a polar O-H bond, but ethanol does. Benzene C6H6 with ethanol C2H6O.

Benzene fails the iodoform test, whereas ethanol does.

While ethanol burns with a non-luminous flame, benzene produces a sooty flame.

Iodoform testing shows that ethanol passes whereas benzene does not.

In contrast to benzene, which generates a sooty flame, ethanol burns with a non-luminous flame.

Water does not mix with benzene, but organic solvents do.

It is a colorless liquid with a pleasant scent.

Benzene has a high melting point and a moderate boiling point.

It burns with a sooty flame and is quite flammable.

A clear, colorless liquid, ethanol has a distinct flavor of burning with a nice aroma. It has high flammability. Ethanol combines easily with water and a variety of organic liquids and is used to dissolve other chemical compounds.

Iron reacts with oxygen gas to produce iron (III) oxide. If there are 52 grams of
IRISSAK [1]

Mass of Fe₂O₃ : 74.26 g

Volume of O₂ at STP = 15.624 L

<h3>Further explanation</h3>

Reaction

4Fe (s) + 3O₂ (g) ==> 2Fe₂O₃ (s)

mol Fe :

Ar Fe = 56 g/mol

\tt \dfrac{52}{56}=0.93

mol Fe₂O₃ :

\tt \dfrac{2}{4}\times 0.93=0.465

mass Fe₂O₃ :

MW Fe₂O₃ : 159,69 g/mol

\tt 0.465\times 159,69=74.26~g

mol O₂ :

\tt \dfrac{3}{4}\times 0.93=0.6975

volume O₂ at STP(1 mol=22.4 L)

\tt 0.6975\times 22.4=15.624~L
