The illustration to the left represents a mixture of nitrogen (blue ) and oxygen (red) molecules. If the molecules in the above illustration react to form NO2 according to the equation N2+2O22NO2 the limiting reagent is the number of NO2 molecules formed is , and the number of molecules in excess is The illustration to the left represents a mixture of hydrogen (light blue ) and oxygen ( red ) reacting to form a product. In the illustration: The product that forms is The number of product molecules formed is The limiting reagent is The number of atoms/molecules in excess is
