Three elements are present in this reaction: carbon, hydrogen, and oxygen. This is typical of combustion reactions, and the completed balanced equation for this reaction is: 4C2H5O + 11O2 --> 8CO2 + 10H2O
H is the chemical formula for hydrogen. There are some elements with H in the chemical formula. But the have other letters too.
There are four elements in the chemical formula NaCOHCl: Sodium (Na), Carbon (C), Oxygen (O), Hydrogen (H), and Chlorine (Cl).
Only one...Oxygen.
The chemical formula of sodium nitrate is NaNO3; the molecule contain Na, N, O.
there are 3 elements - calcium, carbon, and oxygen.
The chemical formula is established after chemical analysis.
