- As pH increases, there is increasingly more H+ than OH-In the formation of water, partial positive and partial negative charges are formed around the hydrogen atoms and oxygen atom, respectively, due to a difference in between hydrogen and oxygen. O Proton Capacity O Hydrogen Bonding Electronegativity ElectroaffinityThe slight positive charge of a hydrogen atom in one water molecule is drawn to the slight negative charge of an oxygen atom in another. This interaction is known as a(n)
- Which of the following terms describes when weak forces are broken, drastically changing the shape of proteins or other large macromolecules? Dehydration Denaturing Dissolving None of the choices. HydrolysisYou are stranded on a lifeboat with several other people in the middle of the ocean. You have run out of clean drinking water and are very thirsty. The others have started to drink the seawater to quench their thirst. Since you’re waiting for rescue (and are a top notch AP Biology student), you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not. a) The majority of dissolved ions in seawater is NaCl, roughly a 0.5M concentration. The ionization constant of NaCl is 2.0. Calculate the solute potential for seawater if you know that the water is 2°C. b) Your own cells have a 0.15M concentration. Calculate the solute potential for your own cells, knowing that body temperature is 37°C. c) Using your knowledge about water potential, if you drink the seawater, wat will happen when the seawater comes into contact with your body’s cells? Note: ΨP for animal cells is zeroWhich of the following statements about pH is (are) true: pH is a measure of free hydrogen ion concentration none of these are true both of these are true An increase in hydrogen ion concentration means a decrease in pH scale units
- Which has more hydrogen ions, grapefruit juice (pH = 3) or tomato juice (pH more or less? tomato, 10x more; O tomato, 10x less; O grapefruit, 10x more; O grapefruit, 10x less; = 4) and how muchIn mixing compounds with water, the polarity of the compounds helps predict their solubility. When a compound's electrons are shared ; if shared unevenly, the compound is evenly, the compound is said to be .Which group dissolves more readily in waterنقطة واحدة The pH value is calculated mathematically as the Log of the * .hydrogen ion (H+) concentration False True O
