If each of the following is an ideal solution at 37 °c, the lowest osmotic pressure, equaling 20 atm, is produced by:

The lowest osmotic pressure is produced by the solution with the lowest concentration of solute.

Explanation:

This relation between the osmotic pressure and the concentration of solute was determined by Jacobus Van 't Hoff and follows the formula:

Where:

Given that R is a constant and that i and T are the same for all  the solutions, the solution with the lowest c will have the lowest osmotic pressure.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
