Question 4 How many electrons in oxygens outer orbital? Question 5 What charge do neutrons carry? Question 6 How many bonds does carbon make? Question 7 How many electrons in hydrogens outer orbital? Question 8 What are the 6 elements that are critical for biology? Question 9 How many electrons in nitrogens outer orbital? Question 10 What does the atomic mass represent? One Question Quiz 10/3/13 Question 1 This is the weakest and most temporary of the interactions covered yesterday. Question 2 What is another term (from model 2) for a nonpolar molecule? Question 3 What type of bond is represented in the picture to the right? Question 4 Which atom is the most electronegative? C, H, or O? Question 5 ________ bonds form between the oxygen atom and each hydrogen atom in a single water molecule. _________ bonds form between the slight negative charge on oxygen in one water molecule and the slight positive charge on a different hydrogen atom. Question 6 What is a cation? Question 7 Polar or nonpolar: O - H Question 8 What is the difference between line and Lewis structure? Question 9 How many bonds does each form? C H O N Question 10 This type of bond forms between a cation and anion. One Question Quiz 10/11/13 Question 1 What is an acid? Question 2 Both cohesion and adhesion result from waters ability to form what? Question 3 What type of substances do not dissolve well in water? Why not? Question 4 How many molecules in a mole of sucrose? Sucrose is C12H22O11 Carbon = 12, Hydrogen = 1, Oxygen = 16 Question 5 What two types of substances dissolve well in water because water is polar? Question 6 How many grams of sucrose in a 1M sucrose solution? Sucrose is C12H22O11 Carbon = 12, Hydrogen = 1, Oxygen = 16 Question 7 What is the importance of solid water being less dense than liquid water? Question 8 What is a base? Question 9 What does it mean when we say that water has a high specific heat? Question 10 How many grams in a mole of sucrose? Sucrose is C12H22O11 Carbon = 12, Hydrogen = 1, Oxygen = 16 One Question Quiz 10/18/2013 Question 1 What reaction joins monomers together and gives off H2O as a byproduct? Question 2 IDENTIFY ANY FUNCTIONAL GROUPS THAT YOU SEE Question 3 What are two types of structural carbohydrates? Question 4 These fats are liquid at room temperature. Question 5 What do unsaturated/polyunsaturated fats have that saturated fats do not? Question 6 IDENTIFY ANY FUNCTIONAL GROUPS THAT YOU SEE Question 7 Steroids belong to this class of macromolecule. Question 8 This process occurs when water breaks the bonds holding polymers together. Question 9 What are β glycosidic linkages? What properties do polysaccharides with β glycosidic linkages have? Question 10 What are two types of storage carbohydrates? One Question Quiz 10/23/2013 Question 1 How is secondary protein structure different from tertiary protein structure?
