Example for Chemical Equation Photosynthesis is the process in plants and certain other organisms that uses the energy from the sun to convert carbon dioxide and water into glucose and oxygen. To get four hydrogen atoms on the right add a coefficient of 2 for the hydrogen gas. CH 4 and CO 2.
Remember coefficients are multipliers so if we write 2 H 2 O it denotes 2x24 hydrogen atoms and 2x12 oxygen atoms.
For example C6H5C2H5 O2 C6H5OH CO2 H2O will not be balanced but XC2H5 O2 XOH CO2 H2O will. A chemical formula is not a chemical name and it contains no words. Na Br 2 -- NaBr. Although a chemical formula may imply certain simple chemical structures it is not the same as a full chemical structural formula.
