Please do both 34. Refer to the table below. Which statement is false regarding chemical bond strength in water with respect to theirstrength in vacuum?LENGTH AND STRENGTH OF SOME CHEMICAL BONDSStrength (kcal/mole)Bond typeLength* (nm)in vacuumin waterCovalent0.109090Noncovalent: ionic bond0.2580Noncovalent: hydrogen bond0.174*The bond lengths and strengths listed are approximate, because the exact valueswill depend on the atoms involved.Covalent bonds retain their strength regardless of the medium because their sharing electrons isindependent of the medium.В.А.When not under vacuum, hydrogen bonds in water decrease by 75% of their strength because they arecontinuously broken and formed.C. lonic bonds decrease by 96% because the strength of the participating ions depends on their charge; inwater, ions will be attracted to water, decreasing the attraction to each other.D.All of the aboveE.

For questions #14-16, you should do your work on a separate piece of paper and then upload it. You should use the GUESS Method of solving for each problem. Also, you have a choice. You can complete both #14 & #15 which are single step question or do the extension problem which is a 2 step problem instead of 14 & 15. You must complete #16.
