Explanation:
It is known that common salt is NaCl and it is ionic in nature. As all ionic substances are able to dissolve in water because like dissolves like.
Hence, salt will easily dissolve in water.
On the other hand, sand is insoluble in water. Therefore, when sand is added to water then it will not dissolve in water.
Thus, we can conclude that when water is added to a sand-salt mixture then sane being insoluble will not dissolve and it will settle at the bottom after some time. Whereas salt being able to dissolve in water will readily dissolve.
False
the correct answer is False.
two or more substances combine chemically
two or more substances combine but keep their physical properties
two or more substances combine and create an irreversible reaction
Mixtures are combination of two or more substances which can be separated based on their physical properties. Hence, option c best describes a mixture.
Mixtures are substances formed by the combination of two or more individual components. The mixing can be of physical or chemical type. The individual components can be separated using some techniques based on their physical properties.
There are both homogenous mixtures and heterogenous mixtures. In homogenous mixtures the components are uniformly mixed and form a single phase.
Heterogenous mixtures are composed of components forming different phases. They can be easily separated using simple techniques. Irrespective of the type of mixing, the physical properties of the components are maintained as such in a mixture. Hence, option c is correct.
