Question

How does a molecular compound compare to the elements that make up the compound?

A
The properties of a compound depend on the identity of the component elements, and not the chemical bonds they fom.
B
The properties of a compound depend on the size of the molecule, and not the component elements
C. The properties of a compound are generally similar to the properties of the elements that make it up
D. The properties of a compound are usually very different from the properties of the elements that make it up

Answer 1

D. The properties of a compound are usually very different from the properties of the elements that make it up

Explanation - Compounds are those substances that are made elements that are combined in a fixed proportion or ratio. If all the elements constituting a compound is same then it is a homogenous compound and even if a single element is different, then it is called as heterozygous compound.

Vapor pressure, boiling point and density are the physical properties of compounds. Compounds also have chemical properties which is visible during a chemical reaction. The elements when combine to form a compound then its individual property is lost.

Answer 2

D

Step-by-step explanation:

The individual properties of the atoms of a compound do not matter anymore because the combined effect of their interactions results completely different properties. The types of bonds formed and the ratio of the elements in the compound, for example, have a huge effect on the properties of the compound. An example is water that is liquid at room temperature while its constitute atoms (those of Hydrogen and Oxygen) are gaseous at room temperature.
