An abundant polar covalent molecule that serves as a solvent, has a high heat capacity, creates a high surface tension, and serves as a. a lubricant b. a substance that dissociates into one or more hydrogen ions and one or more anions c. a substance that dissociates into cations and anions, neither of which is a hydrogen ion or a hydroxide ion d. a proton acceptor e. a measure of hydrogen ion concentration f. a chemical compound that can convert strong acids and bases into weak ones g. a catalyst for chemical reactions that is specific, efficient, and under cellular control h. a single-stranded compound that contains a five carbon sugar, and the bases adenine, cytosine, guanine, and uarcil i. a compound that functions to temporarily store and then transfer energy liberated in exergonic reactions to cellular activities that require energy j. a double-stranded compound that contains a five-carbon sugar, the bases adnenine, thymine, cytosine, and guanine, and the body's genetic material k. a charged atom l. a charged atom with an unpaired electron in its outermost shell

If 1.8 l of water is added to 2.5l of a 7.0 molarity koh solution, what is the molarity of the new solution

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
