How many oxygen atoms are in the products of the following reaction? #C_6H_12O_6 + 6H_2O + 6O_2 -> 6CO_2 + 12 H_2O#
Your equation is suspect. It is supposed to represent the combustion of sugar.
Carbon and oxygen atoms have precise masses and charges. Since mass and charge are conserved in a chemical reaction, it follows that the reactants and the products have equal masses and charge.
In the equation you gave, I could subtract
In the equation given here, there are 18 oxygen atoms in the products. Necessarily there were 18 oxygen atoms as reactants. Is this correct?
