Answer:
1.) Mixture can be defined as the physical combination of two or more substances which can be separated into its different constituents because it's not chemically bound together. A mixture can be homogeneous or heterogeneous.
Step-by-step explanation:
3.) Homogeneous mixture appears UNIFORM while heterogeneous mixture appears IRREGULAR( non - uniform).
4.) A homogeneous mixture is a type of mixture in which the composition is uniform throughout the mixture. While a heterogeneous mixture is a mixture in which different sections have different compositions.
5.) Examples of Homogeneous mixture: the solution of salt and water.
Example of heterogeneous mixture: mixture of sand and water.
From the basic knowledge and definition of mixture in chemistry the above answers had been given.
Furthermore, a mixture contains two or more substances in any proportion. It can be heterogeneous or homogeneous. Examples of mixture include: sea water ( this contains salt and water and can be physically separated) or mud which contains dirt and water.
Homogeneous mixture are said to be uniform in appearance because because the dissolved material is present in the same amount throughout the solution. That is why sea water is known as a typical example.
Heterogeneous mixture are said to be irregular or non- uniform in appearance because the combined substances usually form different phases and layers which can be physically observed. This is seen in a mixture of sand and water or water and oil.
