The difference in the color and consistency of different types of crayons and pastels is due to:

A. the use of different binders. the use of liquid pigmentation.
B. the fact that these media do not need a binding agent.
C. the fact that crayons are made for children, while pastels are made for artists.
D. None of these answers are correct; there is no difference.

A. the use of different binders. the use of liquid pigmentation.

Explanation:

The main difference between crayons and cakes is that they result from the use of different materials. Although both use wax and pigments, the binder changes.

In wax crayons, the binder used is paraffin wax. And in the case of pastels, the binder is a mix of oil and wax with liquid texture.

in this case, the correct answer is A. the use of different binders. the use of liquid pigmentation.

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.
