<span>The answer is 1. Carbon dioxide has two covalent bonds amid every oxygen atom and the carbon atom. When molecules are balanced, though, the atoms pull similarly on the electrons and the control distribution is uniform. Symmetrical molecules are therefore nonpolar.</span>
Answer:
b. Its concentration is half that of the chloride ion
Explanation:
As the calcium chloride formula is CaCl2
CaCl2 <--> Ca + 2 Cl-
Subscripts cannot be changed because they are the ratio of the amount. And as we know, in a chemical equation/reaction, mass cannot be created nor destroyed. Therefore, we cannot change subscripts, however, we could change coefficients. <span />
