Drawing an Electron-Shell Diagram for Oxygen
- Draw an electron-shell diagram for oxygen (8 protons, 8 electrons).
– Electrons of which shell are shared with other atoms?
-How many unpaired electrons are available for sharing with other atoms?
- Using the electron-shell diagram for oxygen you created in the previous question, predict what molecule would result if oxygen were combined with hydrogen atoms (1 proton, 1 electron).
-Draw the electron-shell diagram for hydrogen
-Draw the molecule that would most likely result if Oxygen were combined with Hydrogen.
-What type of bonding exists in this molecule? WHY?
Chapter 3- Water and the Fitness of the Environment
- What type of bonding exists WITHIN a single water molecule?
- Label the partial positive and partial negative charges associated with the atoms the water molecule pictured below.
- As a result of the partial positive and partial negative charges associated with the atoms of the water molecule identified in the previous question, what type of bonding can exist AMONG water molecules?
- Is the association of the two water molecules pictured below likely? WHY?
- Draw a more likely association of two water molecules.
- What is the maximum number of water molecules that one water molecule associate with?
- What is the major difference, in terms of hydrogen bonding, among water molecules in frozen water, liquid water and water vapor?
Draw at least 4 additional water molecules in each illustration.
Frozen water (ice) Liquid Water Water vapor
- Which of the following substances have the highest specific heat? WHY?
- Water = 1 cal/g/ºC
- ETOH = 0.6 cal/g/ºC
- Fe = 0.1cal/g/ºC
- How does water having a high specific heat help permit life on Earth?
- How does water having a high heat of vaporization help permit life on Earth?
- How many grams of the molecule in this figure would be required to make 1 L of a 0.2 M solution of the molecule? (Carbon = 12, Oxygen = 16, Hydrogen = 1)
- How many grams of the molecule would be required to make 2 Liters of a 4 M solution of the molecule?
- What is the pH of a solution with a concentration of 10-8 H+ ions?
-What is the concentration of OH- ions in this solution?
- The pH of a solution is 5. What is the OH- ion concentration?
- If the pH of a solution is increased from pH 8 to pH 9, it means that the
- concentration of H+ is 10 times greater than what it was at pH 8.
B . concentration of H+ is 100 times less than what it was at pH 8.
C . concentration of OH- is 10 times greater than what it was at pH 8.
D . concentration of OH- is 100 times less than what it was at pH 8.
E . concentration of H+ is greater and the concentration of OH- is less than at pH 8.
- Buffer: acid-base pair that work together to maintain pH of a solution
-Which part is called into action when a base is added?
-Which part is called into action when an acid is added?
-What does the acid part do?
-What does the base part do?
- The pH of human blood is approximately 7.4. The buffer that maintains human blood pH is the acid-base pair HCO3-/H2CO3.
- Human blood is ____________.
- slightly basic
- slightly acidic
- neutral
- When a human drinks a large amount of pH 6 fluid the pH of the blood would initially_________.
- Increase slightly
- Decrease slightly
- Stay the same
- What part of the acid-base pair of the buffer that maintains human blood pH would be called into action when a human drinks a fluid at pH 6?
- HCO3-
- H2CO3
- Briefly describe how the buffer described in part C would function.
Chapter 4- Carbon and the Molecular Diversity of Life
- What products were made in Stanley Miller’s experiment?
2A. Draw the electron configuration for Carbon (atomic number 6).
2B. Why do you think this atom is the backbone of all organic macromolecules that make-up living organisms?
- Look at the figure below and determine which pair(s) of molecules is (are) isomers of each other, identifying the type(s) of isomers.
- Circle and name the functional group(s) present in the following molecules.
