31. You add sugar to your coffee, and the sugar dissolves. Thus the coffee is the and the sugar is the a. b. c. d. solute; solvent nonpolar covalent bond; polar covalent bond polar covalent bond; nonpolar covalent bond solvent; solute 32. Near an ocean or other large body of water, air temperatures do not vary as much with the seasons as they do in the middle of a continent. This tendency of water to resist changes in temperature is the result of water's a. b. c. d. high specific heat high density being a good solvent low specific heat 33. Janine has dry skin, so she uses body oil every morning. The oil seals in some of the water on her skin, so that it doesn't get as dry. This is possible because oils a. b. c. d. have a high specific heat are more dense than water are hydrophobic are hydrophilic 34. The brackets are indicating a(n) bond. 8..8 a. ionic b. hydrogen c. polar covalent d. nonpolar covalent 35. To neutralize a solution currently measured at pH 1, you need to add a. base b. vinegar c. water d. acidExplanation / Answer
31 - The correct answer is option D that is coffee is solvent and sugar is solute. Solvent in which we dissolve the substance and solute is the substance that is being dissolved.
32 - The correct answer is option A that is high specific heat because the water molecules as re formed by hydrogen bonds and when temperature increase, hydrogen bonds are broken and when temperature decreases, hydrogen bonds are formed. This property makes water resist to the temperature changes.
33 - The correct answer is option D that is oils are hydrophobic and because of that they are able to seal water molecules. A is wrong because water has higher specific heat. B is wrong because water is more sense than oil. D is wrong because oil is not hydrophilic.
34 - The correct answer is option B that is hydrogen bond.
35 - The correct answer is option A that is base as base will have OH- ions that will neutralize the H+ in pH1 ablution) solution.
