Final answer:
The correct formula for silver oxide is Ag2O, which is based on the ionic charges of silver and oxygen, requiring two silver ions to balance one oxide ion.
Step-by-step explanation:
The correct formula for silver oxide is based on the ionic charges of silver (Ag) and oxygen (O). Silver typically has a +1 charge, and oxygen typically has a -2 charge. By balancing the charges, we need two silver ions to balance the charge of one oxide ion, giving us the formula Ag2O for silver oxide. The options provided suggest various combinations, but we can eliminate them based on the correct ionic charges and stoichiometry. Therefore, the correct formula for silver oxide is option (c) Ag2O.
