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.
H2O is a molecular compound.
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.
