2. Both mixture and compound can be separated.

3. Both mixture and compound have physical properties.

Mixtures and compounds are different in the following ways:

1. A mixture contains two or more substances that are not chemically combined together while a compound contains two or more substances chemically combined together.

2. A mixture can be separated by physical methods while a compound can only be separated by chemical methods.

3. Mixtures can not be represented using a chemical formula. Compounds can be represented by chemical formula.

1.Difference.

Mixtures are physically combined and can be separated by physical means while compounds are chemically combined and are separated by chemical means.

2.Mixtures do not have mixed boiling and melting points while compounds have mixed boiling and melting points.

2.Similarity.

Both mixtures and compounds are composed of two or more substances or elements combined.

Both can be separated.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
