When phillip analyzed an unknown substance x, he found that it contained only one kind of atom. phillip was unable to convert the substance to a simpler one. what is substance x? a. a compound b. an element c. a heterogeneous mixture d. a homogeneous mixture

-

Substance X is a (B) Element.

Explanation: -

A compound consists of either many identical atoms or more than 1 type of atom. They can be broken down or converted into a simpler one.

An element is a substance which contains only one kind of atom. It cannot be broken down further or converted into simpler substance by any chemical means.

Heterogeneous mixture is a non uniform mixture of different atoms without any chemical bonding in between them.

Homogeneous mixture is a uniform mixture of different atoms without any chemical bonding in between them.

From the definitions it is clear that substance X is (B) Element.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
