Stoichiometry
A metal oxide is reduced by heating it in a stream of hydrogen. After complete reduction, it is found that 3.15 gm of the oxide has yielded 1.05 gm of the metal. It may be inferred that the
Sizes of the component molecules are approximately equal
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
Attractive forces between like and unlike molecules are approximately equal
