Question

Jimmy developed a model to show the difference between pure substances and mixtures

Answer 1

1. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances.
2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties.

Explanation:

• A matter which cannot be separated into any other kind of matter using the chemical or physical process is called pure substances. A pure substance has the same color, composition, and texture.
• An element consisting of a single compound with a definite composition, physical and chemical properties are called pure substances.
• A combination that has as of many substances that are not united using a chemical procedure or any process is known as mixtures. A mixture does not exist in fixed proportions, and most of the natural substances are mixtures.
