Question

here are four sketches of substances. each sketch is drawn as if a sample of the substance were under a microscope so powerful that individual atoms could be seen. decide whether each sketch shows a sample of an element, a compound, or a mixture.

Answer 1

A sketch showing one type of atom is an element, a sketch showing different types of bonded atoms is a compound, and a sketch showing different types of non-bonded atoms is a mixture.

Step-by-step explanation:

When we examine a substance under a powerful microscope and see individual atoms, we can determine whether it is an element, a compound, or a mixture. An element is a pure substance made up of only one type of atom, while a compound is a pure substance made up of two or more different types of atoms chemically combined. A mixture is a combination of two or more substances that are physically mixed together.

In order to determine whether each sketch shows a sample of an element, a compound, or a mixture, we need to analyze the individual atoms in the sketch. If the sketch shows only one type of atom, then it is an element. If the sketch shows two or more different types of atoms chemically bonded together, then it is a compound. If the sketch shows two or more different types of atoms that are not chemically bonded together, then it is a mixture.
