The balanced equation for the reaction of nitrogen and hydrogen to form ammonia is given below.What do the numbers in front of the molecules (the coefficients)mean? N₂ + 3 H₂ → 2 NH₃ A) Three moles of H₂ react with one mole of N₂ to give two moles of NH₃. B) Three grams of H₂ react with one gram of N₂ to give two grams of NH₃. C) Three atoms of H react with one atom of N to give two molecules of NH₃. D) Two grams of N react with six grams of H to give eight grams of NH₃. E) All of the above are correct representations.
