Quizplus · Accepted Answer

Statement 1 is true as an individual water molecule is V-shaped with an H-O-H angle of about 105°. Statement 2 is false as the O-H bonds in water are covalent bonds. Statement 3 is also true as water is a polar molecule and can form hydrogen bonds with other polar and ionic substances, increasing their solubility in water. Nonpolar substances do not interact well with polar water molecules, making them less soluble in water. Therefore, choice E (1 and 3) is the correct answer.
