Which statement has an inference mixed in? a. the cells were rectangular and packed tightly together b. the cells were no longer rectangular c. they must have burst when they were microwaved d. in the pond water, there was a small organism moving around very quickly e. there was a white or clear dot inside most of the purplish cells of the red onion

C is an inference. The phrase "they must have" shows that someone tied information together to form a conclusion.

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 atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
