The range of human hearing spans an intensity range of one trillion to one, or 1012 : 1. This is a pretty huge range, and we discussed a couple examples of things that span this range in size. The point of this problem is to come up with a couple of your own examples. Go to this interactive web site, https://htwins.net/scale2
that shows examples of objects at different length scales. Give at least two examples of pairs of objects, where one object is a trillion times larger than the other. (Note that you will need to use a browser that supports flash, or watch the youtube video if your browser doesn't support the interactive version. Also note that the length scale in meters appears in the lower-right-hand corner of the screen.)

The function of this protein is to move protons through a water-filled cavity between the 12 helices. Which two of the following amino acid side chains would be most likely to line this water-filled channel?
Exactly 100 mL of 0.15 M HNO2 is titrated with a 0.15 M NaOH solution. What is the pH at the equivalence point. The Kb of NO2- is equal to 2.2 x 10-11.
What was the PH of the original solution. What are the concentration of all of the following ions at the equivalence point
What is the difference between gluconeogesis and glycogenesis?
a sample of nitrogen gas occupies 1.55 L at 27.0 C and 1.00 atm pressure. What will the volume be -100 C and the same pressure?

What was the mass percent of dissolved solids in the sea water? b.) The actual solution chloride content in the sea water was 2.69%
Identify the two important classes of catalysts. Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
Is it true that the effect of a catalyst on a chemical reaction is to react with product, effectively removing it and shifting the equilibrium to the right
Would you anticipate the bonding orbital(s) of CH to have more C character or more H character or will they have equal amounts of each. Explain how about the anti-bonding orbital(s). Define your reasoning.
You need to load 10 ug of protein into one of the wells of a gel. This needs to be in 1x buffer and in a total volume of 15 uL. You are given a 10 ug/uL solution of protein, a 5x buffer, and water. How much of each should you mix to load the gel c..
