Is a copper wire a mechanical mixture a solution or a pure substance?
It should be a "pure" substance, but its really an alloy.
Mixture in which a substance dissolves into another substance?
Solution. If not maybe Colloid or Suspension.
What makes an Alkaline an Alkaline?
The presence of OH- ions makes an substance alkaline. When dissolved in solution, the substance should be able to liberate OH- ions.
Was the membrane-tubing-permeable to starch?
I'm assuming this is in reference to an experiment where you put a starch in dialysis tubing, and then put iodine in surrounding solution. Dialysis tubing has a limit of roughly mwco (molecular weight cut off of 10,000). Iodine has a molecular weight of roughly 126, so it can pass through. On the other hand, starch is a polymer of 1000's of glucose molecules. Glucose (C6H12O6) has a molecular weight of roughly 180. 1000 * 180 = 180,000, so glucose cannot pass through the dialysis tubing. In this experiment you should see the sealed tubing turn purple-pinkish after the iodine diffuses through. The outside solution should remain the same color.
Why do air bubbles form in body after periotenal dialysis?
periotenal dialysis can be done at home. But it should be done every day. During the process of dialysis a small air bubble that enters the blood stream can reach any part of the body.
The substance present in the largest amount in a solution?
Solute. No, I believe the answer should be 'solvent'.

What is appearance of solution?
A definite qty. of substance is dissolved in definite amount of solvent solution should be clear.
What would happen to the weight of a dialysis bag filled with molasses placed in a beaker of water?
The water in the dialysis bag would diffuse out into the molasses solution. This is because there is a high concentration of water inside the dialysis bag and a a lower concentration of water in the molasses solution. By diffusion or osmosis, the water would tend to move from the concentrated bag to a less concentrated solution.

What is the definition of a solute?
Don't really know.....you should ask someone
What is appearance of the solution?
A definite qty. of substance is dissolved in definite amount of solvent solution should be clear.
The more-abundant substance in a solution?
in any solution the substanse with the greatest quanity is the
What substance should you add to salt to make it less concentrated?
Assuming you mean a solution of salt, you would add WATER.
Is rum and Coke a homogeneous mixture?
Since rum is alcoholic, solution should be homogeneous.
Can dialysis patients take Advil?
Standard dosages of ibuprofen should not be a problem if the patient is on dialysis. However, most dialysis patients have concomitant heart disease, vascular disease, and or diabetes. It is on those grounds they should not take ibuprofen unless they are on a daily aspirin. Patients with kidney disease and not on dialysis should NOT take ibuprofen or other NSAIDS as this may have been contributory to their renal disease in the first place.
