Answer:
In chemistry, a mixture is a substance made up of 2 or more substances that are not chemically combined, but physically combined. This means there are no chemical bonds between the different substances in a homogeneous or heterogeneous mixture. You can think of a salad as an example of a mixture— lettuce, tomatoes, cucumbers, and Parmesan cheese are substances, and each substance retains its own chemical composition and identity.
A homogeneous mixture (from the root “homo” meaning same) has a uniform composition throughout. Furthermore, in a homogeneous mixture, all substances exist in one state of matter. Liquids can be homogeneously mixed with liquids, solids with solids, and so on.
Examples :
1)Saltwater
If salt dissolves in water, it disperses evenly throughout the water. Note that seawater can be heterogeneous if pieces of particulate matter are present, as in nature.
2)Coffee, milk
These drinks consist of many chemicals dissolved in water, spread evenly like in saltwater. However, when milk curdles, it becomes a heterogeneous mixture.
3)Cement, glue
These are homogeneous mixtures of chemicals that set (harden) on drying or exposure to other special conditions. They may have other things added which could make them heterogeneous.
4)Bronze, steel
These are alloys, made by mixing copper and tin (for bronze) or iron and carbon (for steel). Because the resulting mixtures do not have distinguishable regions of each component, they are homogeneous.
5)Air
Air is a mixture of gases spread evenly throughout the atmosphere. Because gas molecules are distant from one another, they always mix evenly and do not form heterogeneous mixtures.
Other examples include :
6)Mouthwash
7)Detergent
8)Cologne
9)Jello gelatin
10) Sugar syrup
