Answer: CaO ( For the subscripts 1,1)Explanation: In order to determine the possible subscripts of the element or molecule you need to see the charges that each element has In this case Ca, i.e., the calcium has a charge of +2. The charges are present in the element due to the inequality in the number of electrons. Items that have a positive charge are called cations Or that is to say, the Oxygen has a charge of -2 and are also present due to the odd number of electrons. Items that have a negative charge are called anions. Both the charges +2 Ac and -2 Or canceled and will result in CaO
