Please select the word from the list that best fits the definition Composed of one type of compound molecule compound mixture chemical formula molecular formula pure substance

Pure substance

Explanation:

Molecule: contains more atoms of different elements. An example is CO2 molecule. So this option is wrong.

Compound: All compounds are molecules so this option is also wrong.

Mixture: Refers to the union of more than one substances that can be separated.

Chemical and Molecular formular: Represents the constituents of a molecule. This is wrong.

Pure substance: This is the correct option. For an object to be considered pure, it must be composed entirely of one compound.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
