Which food is not a heterogeneous mixture?
a. chocolate chip cookies
b. oil and vinegar dressing
c. cooking oil
d. trail mix

Option C cooking oil is not heterogenous mixture

Explanation:

Mixture is a combination more than two substances and are not chemically combined.

It is of two types Homogenous mixture and heterogenous mixture

Homo means “same”.

Hetero means” different”

Homogenous mixture is a mixture which looks uniform throughout

Examples Cheese, salt solution, air, 18 carat gold

Heterogenous mixture is a mixture which looks non uniform throughout

.Examples Pizza, trail mix, salad, A mixture of oil and water

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.
