Titanium dioxide is a type of mixture if particles of titanium dioxide are insoluble in the liquid.
<h3>What is a mixture?</h3>
A mixture is composed of one or more pure substances in varying compositions.
A mixture is a material made up of two or more components joined together, but not chemically combined. In a mixture, a chemical reaction does not occur and each of its components maintains its identity and chemical properties.
A compound is a substance formed by the chemical combination of two or more different elements from the periodic table. The elements of a compound cannot be divided or separated by physical processes. They are not mixtures or alloys
An element is a type of matter made up of atoms of the same class. It is an atom with unique physical characteristics, a substance that cannot be decomposed by a chemical reaction.

Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Explanation:
Given: n = 2
The relation between energy and orbit of an atom is as follows.
Substitute the values into above formula as follows.
The negative sign indicates that energy is being released.
Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
