Which equation obeys the law of conservation of mass? h2(g) + o2(g) → h2o(g) h2(g) + o2(g) → h2o(g) +4he(g) 2h2(g) + o2(g) → 2h2o(g) h2(g) → h2o(g) h2(g) + o2(g) → 2h2o(g)

The correct answer is 2H2(g)+O2(g)->2H2O(g)

the answer is Option C

idk

explanation:

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.
