One last question, can anyone help me with these odd chemistry problems...

Discuss two advantages to constructing molecular models as opposed to just drawing them.
and.....

Using the same ideas from above, why do you think water is not used to dissolve greasy stains?

I am forever in debt to whoever can assist me . Thank You
This will help me for my exam
 
molecular models are 3d as opposed to 2d drawings giving the viewer a better idea of the size and shape of the molecule. You can also use models to show the function of said molecule.

water cannot dissolve grease stains because grease and fat are hydrophobic or insoluble in water so a detergent must be used to break them down.
