Which substance is a mixture? salt gasoline aluminum carbon dioxide

gasoline

Explanation:

Element is a pure substance which is composed of atoms of similar substances.It can not be decomposed into simpler constituents using chemical reactions.Example: Aluminium

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: carbon dioxide and salt

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: gasoline which is a mixture of different hydrocarbons.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
