formation of water and hydrogen peroxide , carbon dioxide and carbon monoxide are the big examples of law of definite proportion
They are elements
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
Molecules that contain only carbon and hydrogen are called hydrocarbons. Some examples are methane, CH4, ethane, C2H6, and propane, C3H8.
