Anumber of substances and their chemical formulas are listed below. check the ones that are compounds.

neon (ne)

carbon monoxide (co)

glucose (c6h12o6)

cobalt (co)

fluorine (f2)

The correct answer is Carbon monoxide (CO) and Glucose (C6H12O6).

A compound is substance, which is formed by two or more chemical elements  bonded together in the fixed ratio.

Carbon monoxide is made from Carbon and oxygen. Similarly, glucose is made by three elements that is Carbon, hydrogen, and oxygen.

On the contrary, neon, cobalt, and fluorine are made up of single elements. Therefore, they are not compounds.

Thus, Carbon monoxide (CO) and glucose (C6H12O6) both are compounds.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
