Calculate the number of molecules of Al2O3, that are produced when 5.5 mol of Fe is produced in the following reaction. 2Al(s) + 3FeO(s) + 3Fe(s) + Al2O3(5) 2.4 x 1023 molecules 1.1 x 1024 molecules b. 1.2 x 1023 molecules d. 3.6 x 1023 molecules ​

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
