Explain what is meant by a scientific theory by giving the three ship canal your text prepares a theory from a hypothesis or unpolluted speculation. Chapter 2 The Chemical Context of Life 2. 3. This chapter covers the basics that you may have learned in your chemistry class. The questions that follow should help you focus on the most important points. Matter grammatical constituent trace element neutron nuclear get atomic mass energy polar covalent flummox anion mix proton iso baksheeshe electronegative action dynamic equilibrium essential element electron electron shells monopoly covalent bind total heat bond Concept 2. Matter consists of chemical elements in pure form and in combinations called compounds 1. What quaternity elements make up 96% of all living matter? Concept 2. 2 An elements properties depend on the structure of its atoms 2. Below is a gravel of an atom of helium, correctly label the electrons, protons, neutrons, and atomic nucleus. 3. What is the atomic number of helium? Its atomic mass? 4. Consider this entry in the triennial table for carbon. What is the atomic mass? Atomic number? How many electrons does carbon have? Neutrons? 5. What are isotopes? Use carbon as an example. 6.Explain radioactive isotopes and one medical examination application that uses them. 7. Which is the only subatomic particle that is directly involved in the chemical voices between atoms? 8. What is electric potential energy? 9. Explain which has more potential energy in each pair a. Boy at the top of a slide/boy at the bottom electron in the third energy shell the chemical behavior of an atom? B. electron in the first energy shell/ c. Water/glucose 10. What determines a. How many valency electrons does it have? B. How many protons does it have? Concept 2. 3 The formation and bit of molecules depend on chemical bonding between atoms 12.Now, refer hold to your definition of a compound and fill in the following chart corpuscle? (y/n) Compound? (y/n) Molecular Formula Water Carbon dioxide Methane geomorphological Formula 02 13. What type of bond is seen in 02? Explain what this means. 14. Choose the correct labels for the electron distribution diagram of peeing. Which element is most electronegative? Molecule? Why is water considered a polar (This is a very important concept. Spend some time with this one ) 15. Another bond type is the ionic bond. Explain what is happening in the figure below (2. 14) 16. What two elements are involved above? 17.In the preceding example, which is the anion? 18. Indicate where the hydrogen bond occurs in this figure. Hydrogen 19. Here is a list of the types of bonds and interactions discussed in this section. On the chart hydrogen bonds, van deer Walls interactions, covalent b onds, ionic bonds. new wave deer Walls interactions 20. What is the biological importance of weak bonds? 21 . Use morphine and endorphins as examples to apologize why molecular shape is crucial in biology. Concept 2. 4 Chemical reactions make and break chemical bonds 22. print the chemical shorthand equation for photosynthesis. Label the reactants and the products. 23.For the equation you Just wrote, how many molecules of carbon dioxide are there? How many molecules of glucose? How many elements in glucose? Chapter 3 Water and the Fitness of the Environment polar molecule ad hoc heat solute pH cohesion evaporation hydrophilic acid adhesion upshot hydrophobic base Concept 3. 1 The polarity of water molecules results in hydrogen bonding 1. Why is water considered polar? 2. How many hydrogen bonds can a single water molecule form? Concept 3. 2 Four emergent properties of water contribute to Earths fitness for life Hydrogen bonding accounts for the unique properties of water. Lets look at several.Cohesion 3. What is demonstrated when you see beads of water on a waxed car jacket crown? Calorie solution military . Which attribute explains the ability of a water strider to walk on water? Moderation of Temperature 5. Water has laid-back specific heat. How does waters specific heat compare to alcohols? 6. Explain how hydrogen bonding contributes to waters high specific heat. 7. Summarize how waters high specific heat contributes to the moderation of temperature. How is this property important to life? 8. What is heat of vaporization? Explain at least three effects of this property on living organisms. Expansion upon freeze 9. Ice floatsSo what? Consider what would happen if ponds and other bodies of water roll up ice at the bottom. Describe why this property of water is important. 10. Now, explain why ice floats. Why is ICC the critical temperature in this story? resolving power of Life 1 1 . Consider coffee to which you have added sugar. Which is the issue ? The solute? 12. Explain why water is such a fine solvent. 13. You already know that some materials, such as olive oil, will not dissolve in water. In fact, oil will float on top of water. Explain this property in terms of hydrogen bonding. 14. Now, lets do a little work that will enable you to prepare solutions.Read the section on solute concentrations carefully, and show the calculations here for repairing a I-molar solution of sucrose. move to help you do this follow. The first step is done for you. Fill in the rest. Steps to prepare a solution a. Write the molecular formula. B. Use your periodic table to calculate the mass of each element. Multiply by the number of atoms of the element. (For example, O has a mass of 16. Therefore one mole of O has a mass of 16 x 11 = 176 g/mole. ) tidy sum of each element in the molecule. C. Add the d. Add this mass of the compound to water to bring it to a volume of 1 liter.
