5. What is the difference between mixtures and compounds?
Mixtures
Elements and compounds are mixed to form a mixture.
The constituents in the mixture can be separated.
Components of mixtures have variable compositions.
The mixture displays all the properties of constituent substances.
Compounds
Elements react to form new compounds.
Compositions of the particles of compounds are fixed.
The separation of the constituents can be done only chemically.
The new substance has different properties.
6. What are the applications where Chromatography is used?
The applications where chromatography is used are separating the colours in the dye, separating pigments from natural colours, separating drugs from the blood. There are many advanced techniques of Chromatography that you will study in detail in the higher classes. There are also courses and subjects in this topic . This is a vast and interesting subject and some students might be interested to take there.
7. What is the Heterogeneous Solution?
A heterogeneous mixture is a type of mixture where the components are not in a uniform composition. Heterogeneous mixtures can be separated physically, and the components are in smaller amounts. Sodium chloride and sand are examples of heterogeneous mixture. These are very important topics when it comes to chemistry. The difference of each should be understood properly so there is no confusion in later stages.
8. Define mixture and solution.
Mixture contains either two or maybe more compounds. These compounds are not chemically combined. They are combined physically while the chemical properties in the mixture remain unchanged. The amount of a substance in a mixture can vary. The solution is a homogeneous mixture because the composition stays uniform throughout the solution. The composition of the solution has solvent and solute, and the solvent always dissolves the solute, and it is in higher quantity.
