Which of the following statements about pH is/are true? a. A single unit change on the pH scale is equivalent to a 1% change in hydrogen ion concentration b. An increase in hydrogen ion concentration means a decrease in pH scale units c. pH is a measure of oxygen ion concentration d. pH stands for percent hydrogen e. None of the choices are true 4. A hypothesis a. Is a tentative explanation for a specific phenomenon b. Is the same as a theory c. Is an explanatory idea that is broad in scope and supported by a large body of evidence d.

KRAUZ – BIO(H) 5. The temperature of evaporation is much higher for water than for alcohol. Without knowing more about the chemistry of alcohol, which of the following is the most logical chemical explanation for this phenomenon? a. Fewer hydrogen bonds form between alcohol molecules. As a results, less heat is need for alcohol molecules to break away from solution and enter the air b. Ionic bonds form between alcohol molecules. These are the weakest type of bond and are easier to break than the hydrogen bonds between molecules c. Alcohol molecules are more cohesive than water molecules. This means that as alcohol molecules evaporate, they pull other alcohol molecules into the air along with them. d. Alcohol has a higher surface tension than water. This means that alcohol molecules can easily break away from other alcohol molecules and evaporate at a lower temperature e. None of the choices is a logical chemical explanation for this phenomenon 6. Hydrocarbons a. Consist of atoms linked exclusively by single bonds b. Are inorganic compounds c. Are composed of carbon atoms that are attached to hydrogen skeletons d. Contain only carbon and hydrogen atoms e. All of the choices are correct 7. Organisms that are NOT prokaryotes are in the Domain a. Bacteria b. Archaea c. Monera d. Eukarya e. Eubacteria 8.
