... so on the right hand side we have 2 CO2 + 3 H2O, and thus 2 x 2 + 3 = 7 O atoms. On the left hand side we have 1 O atom in ethanol, so we must provide 6 O atoms from O2 and thus we must have 3 O2, so the balanced equation is C2H5OH + 3 O2 2 CO2 + 3 H2O: 2C + 6H + 7O both on the left and on the rig ...

The equation must be balanced to reflect the law of conservation of mass, which states that matter can neither be gained nor lost in the process of a chemical reaction. Balancing Chemical Equations The chemical equation enables the determination of the quantity o ...
