C(s)+ 1 /2 O 2 (g) CO(g) CO(g)+ 1 /2 O 2 (g) CO 2 (g) How will oxygen appear in the final chemical equation?

Answer : The oxygen will appears in the final chemical equation as a reactant.

Explanation :

The given chemical reactions are:

(1)

(2)

Now we are adding reaction 1 and reaction 2, we get the final chemical equation.

The final chemical equation is:

Thus, the oxygen will appears in the final chemical equation as a reactant.

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.
