Question

A scientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas.

Answer 1

Correct answer choice is:

They are all matter. Some are compounds made of one type of element. Some are pure elements.

Explanation:

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.

Answer 2

The best description is provided by the statement:
They are all matter. Some are compounds made of one type of element. Some are pure elements.

Matter is defined as any substance that has mass and takes up a space (volume). Water and carbon dioxide are compounds made of different elements, while silver and oxygen are pure elements.
