What are the respective formulas for iron (ii) oxide and carbon tetrachloride? what is the difference? a) fe2o - they are both ionic. b) feo and ccl3 - one is ionic and the other covalent. c) fe2o - they both share valence electrons to complete the valence shells. d) feo and ccl4 - one has charges that keep the ions bonded and the other does not.

D) FeO and CCl4 - One has charges that keep the ions bonded and the other does not.

Explanation:

Hello,

In this case, for the iron (II) oxide, in order to know its formula, it is necessary to realize that the (II) indicates the oxidation state it has, it meas +2 from the roman number translation, in such a way, by knowing oxygen works with -2, therefore, the formula turns out:

In addition, for carbon tetrachloride, the prefix tetra before chloride, points out there are four chlorined bonded to the carbon, that is why its formula is:

In such a way the answer is D) FeO and CCl4 - One has charges that keep the ions bonded and the other does not.

Best regards.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
