Circle the word of phrase that correctly completes the sentece or answers the question. The property that allows water molecule to be attracted to each other is called (cohesion, adhesion). This propert is conferred by (covalent bonds, hydrogen gonds). This property is conferred by ( covalent bond, hydrogen bond). Ice is ( more dense, less dense) than liquid water. Water is polar molecule because of the unequal sharing of( electrons, protons) between the atoms in H2O. Adhesion of water to a surface is through the action of (covalent bond, ionic bonds, hydrogen bonds) between the water and the surace. Water is converted from liquid to vapor through the brakage of ( colvalent, hydrogen) bonds. Which (one) of these substance is not hydrophilic:( cellulose, oil, NaCl). Which of these will not dissolve in water, even though it is polar?(cellulose, oil, NaCl). Which of these is an electrolyte? (cellusose oil, NaCl). A buffer will contain a week acis , weak base, both).
