Answer:

<h3>D)Moon and sun</h3>

Explanation:

Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.

How might the geometry of the product change (oh in an endo or exo position?) if all the methyl groups of camphor were replaced
Greeley [361]

Replacement of methyl groups of camphor is a reduction mechanism. Camphor is a bridged bi-cyclic compound. If you observe the structure of camphor the methyl group is placed with one carbon bridge (7, 7) and two carbon bridge (1). Attack from face of one carbon bridge is termed as exo attack whereas from face of two carbon bridge is termed as endo attack. So replacement will lead to mix of both and formation of two stereo isomers.

Reduction mechanism is often shown with a U-shaped arrow pointing the attack by ion such as in nucleophilic addition reaction.

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.

Dmitry_Shevchenko [17]

The <u>Mole</u> is the SI unit that expresses the amount of substance.

Mole is defined as - The mole is the amount of substance containing the same number of entities as there are in the 12 grams of Carbon - 12.

Mole is denoted by using symbol mol.

      Mole = 6.022 x 10²³ elementary entities.

These number of elementary entities in 1 mole is equal to or called as an Avogadro's number.  Mole is equal to 6.022 x 10²³ because this number of entity is same as in exactly 12 g of carbon-12.

It is a very important SI unit of measured which is used by the chemists. Moles are used in measuring in small or tiny things such as atoms, molecules and the other tiny particles.
