Achemical equation is shown: ai+ o2 → al2o3 according to the law of conservation of mass, how many atoms of oxygen exist in the products of this reaction? a) 6 b) 5 c) 3 d) 2

The answer is A because you have to balance the equation first then answer.

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.
