<h3>What are mixtures?</h3>
Mixtures are the compounds which are formed by the addition or combination of one or two elements or compounds.
As in the mixtures many states of matters are present and it will be filtered by using various physical methods, and it is not chemically shown by single chemical symbol or formula. Mixtures are also of two types:
- Homogeneous mixtures are those in which equal compositions all over the volume is present.
- Heterogeneous mixtures are those in which different composition all over the volume is present.
Hence options (1), (3) and (4) are correct.
