The following equation represents dissolving a molecular compound in water:

[tex]\[ \text{Urea (s)} \rightarrow \text{Urea (aq)} \][/tex]

1. a) How many "particles" are produced in solution for every molecule of urea that dissolves?

b) Can a solution of urea conduct electricity? Why or why not? Look at the structure of urea on page 1 and re-read the section on page 2 titled "More information on the two solutes" to help with this answer.



Answer :

GinnyAnswer

Final answer:

Urea dissolves in water to produce two particles per molecule, but the solution cannot conduct electricity due to the lack of ion formation.


Explanation:

Answer:

a) How many particles are produced in solution for every molecule of urea that dissolves?

When urea dissolves in water, it produces two particles in solution for every molecule of urea that dissolves. This is because urea dissociates into urea ions in solution.

b) Can a solution of urea conduct electricity?

A solution of urea cannot conduct electricity because urea does not break apart into ions in solution, which are needed for the conduction of electricity. Since urea remains mostly as neutral molecules, it does not enable the flow of electrical current.
