How Do I Make a Mixture? How Do I Make a Compound?

Answer 1

A mixture occurs when you combine matter in a way where the components can be separated again. A compound results from a chemical reaction between components, forming a new substance. For example, you can combine iron filings with sulfur to form a mixture. All it takes is a magnet to separate the iron from the sulfur. On the other hand, if you heat the iron and sulfur, you form iron sulfide, which is a compound.
Difficulty: Easy
Time Required: Minutes
Here's How:

1. First form a mixture. Stir some iron filings and sulfur together to form a powder. You have just taken two elements and combined them to form a mixture. You can separate the components of the mixture by stirring the powder with a magnet (iron will stick to it) or by swirling the powder with the magnet under the container (the iron will fall toward the magnet at the bottom - this is less messy).
2. If you heat the mixture over a bunsen burner, hot plate, or stove, the mixture will start to glow. The elements will react and will form iron sulfide, which is a compound. Careful! Unlike the mixture, the formation of a compound can't be undone so easily. Use glassware that you don't mind ruining.

Tips:

1. When you form a mixture, you can add components in any ratio that you want. It doesn't matter if there is more iron than sulfur, for example.
2. When you form a compound, the components react according to a set formula. If there is an excess of one or the other, it will remain after the reaction that forms the compound. For example, you may have some leftover iron or sulfur in the tube with your mixture. 2 g of sulfur with 3.5 g of iron filings will completely react.

What You Need:

* iron filings
* sulfur (powder or flowers of sulfur)
* magnet
* test tube or beaker
* burner or hot plate or stove..

Answer 2

A mixture is a combination of substances that does not affect the chemical nature of the components. A glass of Iced tea is a mixture. A compound is a combination of 2 or elements that does alter the chemical nature of the components. Burning hydrogen gas in the presence of oxygen will form water. Hydrogen and oxygen are elements that are gases at room temperature. When combined, they form water which is a liquid at room temperature.

Mixture: When the components does not mix with.....
Compound: When the components mix among themselves...
