A scientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas. Which group of statements best describe all of the materials he is using in the investigation?

A. They are each compounds. Each of the compounds is made of atoms. All of the atoms are made of matter.

B. They are each made of matter. Some are compounds and some are elements. They all contain atoms.

C. They are all elements. Some contain molecules of the same type of atom. Some contain different types of atoms.

D. They are each made of matter. Some are compounds made of one type of element. Some are pure atoms.

The matter is a substance that has inertia and holds bodily area. According to advanced physics, matter consists of several kinds of particles, each with volume and area.

A pure element indicates a substance whose atoms possess the equivalent atomic number or number of protons.

Silver is extensively utilized as a manufacturing catalyst for the composition of ethylene epoxide via ethylene oxidation and for formaldehyde via methanol oxidation. Oxygen classes on silver are determined to perform a pivotal use in ethylene epoxidation and particular methanol oxidation.

The outcome of the reaction between hydrogen gas and oxygen gas is water vapor (gas).

Water and carbon dioxide are compounds composed of various elements, whereas, silver and oxygen remain pure elements.
