Light passes straight through a solution without scattering. By contrast light passed through a(n) will scatter because the dispersed particles are similar in size to the wavelengths of visible light. This phenomenon is known as the effect and is an important tool in distinguishing between the different types of mixtures.

The answer is "colloid and Tyndall".

Explanation:

In this question when the sunlight goes through a scattered solution. Contrasting light that passes by a colloid will expand also because particles dispersed have the same size as visible light on the wavelength. This technique is known as Tyndall and is a vital means to distinguish combinations from each other and.

i think its 100.

hope this !

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
