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.
Glucose is a molecular compound, not ionic. It consists of covalent bonds between its carbon, hydrogen, and oxygen atoms.
HCIO4 is an ionic 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.

CO is a molecular compound. It consists of a covalent bond between carbon and oxygen atoms.
Ionic bonds are strong, molecular bonds are relatively weak.
Anhydrous H2CO3 (carbonic acid) is molecular, not ionic. It does not dissociate into ions in the absence of water.
