the answer to your question is what and x
Option (c) is the correct answer.
A molecule is defined as a substance which can contain atoms of same or different elements that are chemically combined together.
For example, , , etc are molecules.
Whereas a compound is defined as a chemical specie which is made by the combination of different atoms in a fixed ratio by mass.
For Example, , etc. are compounds.
A compound will also be considered as a molecule but a molecule can never be considered as a compound.
And, a molecule of an element will always contain atoms of one type of element.
As in the given situation both W and Z atoms represent the same element, that is, oxygen.
Thus, we can conclude that W and Z atoms could join together to form a molecule of an element.
this chart shows four atoms, labeled w, x, y, and z. these atoms can combine w...
