Question 21 ptsWhich of the following statements about solution formation is FALSE?In the dissolution process; intermolecular forces between solute and solvent particles must be disruptedEnergy must be consumed to disrupt solute-solute interactions during solution formationNonpolar solutes tend to dissolve in nonpolar solventsEnergy is released when solute-solvent interactions form during solution formationPolar solutes tend to dissolve in polar solvents

Question 2 1 pts Which of the following statements about solution formation is FALSE? In the dissolution process; intermolecular forces between solute and solvent particles must be disrupted Energy must be consumed to disrupt solute-solute interactions during solution formation Nonpolar solutes tend to dissolve in nonpolar solvents Energy is released when solute-solvent interactions form during solution formation Polar solutes tend to dissolve in polar solvents



Answers

Indicate whether each statement is true or false: (a) A solute will dissolve in a solvent if solute-solute interactions are stronger than solute-solvent interactions. (b) In making a solution, the enthalpy of mixing is always a positive number. (c) An increase in entropy favors mixing.

Statement, eh? Is false. Should read the vapor Pressure of a solution is directly related to the mole. Fraction of solvent ending should be changed from of saw Ute two of so event to make it true. Statement be when Salyut is added to water, the water in solution has a lower vapor pressure than that of pure race at zero degrees Celsius. The statement is true. Statement See Collective Papa Colligan of properties depend on Lee on the identity of the Salyut and not on the number of Saul you particles present. This is false. The statement is written backwards and should read. Collect Colligan of properties depend on the number of Saul you particles present so depend on the number off saw ute particles present and not on the identity of the salute statement deep. When sugar is added to water, the boiling point of the solution increases above 100 degrees Celsius because sugar has a higher boiling point than water. This statement is also false and should be corrected to read because sugar dissolved in water lowers the vapor pressure, which is why the boiling point is elevated

Statement. A. His false should read. The vapor pressure of a solution is directly related to the mole. Fraction of solvent ending should be changed from of saw ute two of so event to make it true. Statement be when Salyut is added toe water. The water in solution has a lower vapor pressure than that of pure race at zero degrees Celsius. The statement is true. Statement see Collective per pop Colligan of properties depend on Lee on the identity of the Salyut and not on the number of Salyut particles present. This is false. The statement is written backwards and should read. Collect Colligan of properties depend on the number of Saul you particles present so depend on the number off saw ute particles present and not on the identity of the Salyut statement deep when sugar is added toe water, the boiling point of the solution increases above 100 degrees Celsius because sugar has ah higher boiling point than water. This statement is also false and should be corrected to read because sugar dissolved in water lowers the vapour pressure, which is why the boiling point is elevated

So here we have some different statements to consider. So we've got a B and C so with a solution prepared in water, this is an adequate solution. So this is true. The next one. The Net Ionic equation cannot be written where no chemical reaction occurs as irons do not interact again. This is true. We cannot have a sort of any sort of chemical equation if no reaction has even occurred. Lastly, the precipitate formation leads to cloudiness within the solution, and again, that is true.

Okay. Were asked to determine whether the statements are true or false. If you dissolve acetone and water. Acetone is CH three oh CH three. It's a molecular species and it's not going to for many ions so there's no way for it to conduct electricity. So conducting solution will not result in. The statement is false. Now when ammonium nitrate dissolves in water, it's going to be an H4. I know three. First of all the solution is not weekly conducting. It is strongly conducting because so it's already false because it's going to fully ionized. This is a uh highly soluble compound. Oh And then um I know three doesn't hide relies any further but the NH four plus. Well so let's see if it's acidic or basic. So it's going to form Yeah. Yeah. NH three. Sure. Plus. HD A plus When it reacts with water. Um so it's actually gonna be acidic in nature because you form H20 plus. Um So it's wrong on both counts and therefore the statement is very false.
