The reaction of 50 ml of n2 gas with 150 ml of h2 gas to form ammonia via the equation: n2 (g) + 3h2 (g) → 2nh3 (g) will produce ml of ammonia if pressure and temperature are kept constant.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
