Question

formula of calcium oxide
explain with cross method​

Answer 1

Answer:

Formula and structure: Calcium oxide chemical formula is CaO and its molar mass in 56.0774 g mol-1. The molecule is formed by the calcium cation Ca+2 and the oxygen anion O-2, which form a ionic bond. The calcium oxide ionic lattice is cubic and similar to NaCl lattice, with an ion surrounded by 6 opposite charge-ion.
