How are prefixes used to name compounds? O A. A prefix is used only for the name of the second element in
covalent compounds.
B. Prefixes are used to tell how many of each kind of atom are in
covalent compounds.
C. Prefixes are used to tell how many of each kind of atom are in
ionic compounds.
O D. Prefixes are used to indicate the number of atoms in both covalent
and ionic compounds.

(answer is B) :)

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.  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
