The correct chemical equation is:

C6H12O6   +   6 O2 -->  6 CO2   +   6 H20

 

Chemical equations must balance so that there are always equal numbers of atoms of each type on the left (reactants) and on the right (products).  Balanced chemical equations show the number of moles of each reactant and product in the reaction. This ensures that there are equal numbers of atoms of every element on both sides of the equation.

C6H12O6  +  ___6___O2 ----------------------> __6___CO2  +  _6__H2O

Chemical equations must balance so that # of atoms in reactants = products.

According to the Law of conservation of mass.

C6H12O6  +  ______O2 ----------------------> _____CO2  +  ___H2O

C6H12O6 + 602 ------> 6C02 + 6H2O

then you will have 6 carbons, 18 oxygens and 12 hydrogens on both sides
