It seems like you may be referring to the molecular formula for water, which is H2O. Water is a covalent compound made up of two hydrogen atoms and one oxygen atom.
Cr2O3 is an ionic compound. It consists of chromium ions (Cr3+) and oxide ions (O2-) held together by ionic bonds.
H2O is a molecular compound.
The chemical formula "CH" does not correspond to a stable compound. "C" is the symbol for carbon and "H" is the symbol for hydrogen, but they would typically be found in compounds with multiple atoms of each (e.g. methane, CH4). If you meant something different with "CH", please provide more context.
NO is a molecular compound, not an ionic compound. It is made up of individual atoms of nitrogen and oxygen that are covalently bonded together.
The molecular formula of sulfur dioxide (SO2) is molecular, not ionic. This compound is made up of covalent bonds between sulfur and oxygen atoms, where they share electrons to form the molecule.
