Please help me with my 8th grade chemistry, I'm really confused
The Law of Conservation of Mass states that mass can neither be created nor destroyed. In which of the following situations does this law apply?
a. in neither chemical nor physical changes
b. only in chemical changes
c. in both chemical and physical changes
d. only in physical changes

The answer would be C, in both chemical and physical change, because everything is made up of matter. So if you have a chemical or physical change, that doesent change the total mass of your product ever.

Explanation:

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.
