Question

SOME HELP PLEASE

Answer 1

Answer:

A substance made of two or more types of atoms that are not chemically bonded

Explanation:

Mixtures are systems made up of two or more compound or simple substances that are different. Thus, they present undefined and variable physical properties. These properties depend on the amount of each substance in the mixture and the nature of them. In other words, a mixture is a substance composed of two or more types of atoms that are not chemically bonded.

Mixtures can be classified as homogeneous and heterogeneous. In the case of hydrated alcohol, we have a homogeneous mixture. But what is a homogeneous mixture? It is a mixture in which we cannot see the separation of its components. Its entire length is uniform and has a single phase. Heterogeneous mixtures, on the other hand, are those that have more than one phase, such as the mixture of water and oil, water and sand, granite (mixture of quartz, mica and feldspar) and so on.

Answer 2

Matter that is composed of a single element and has all the same physical properties would be a substance

Matter that is made of molecules of all the same type are elements

Two atoms chemically bonded together is a compound

A substance made of two or more types of atoms that are not chemically bonded is a mixture

the last one is correct answer
