1. In determining the half-life of barium-137m, it was not necessary to subtract out the background. Why not?
2. You used a strontium-90 source in Part C of this experiment. Write the balanced equation showing this beta decay.
3. In many instances in these experiments, you might have tried to make identical measurements but obtained different values of the Activity. How can that be? Hint: It’s probably not operator error.

Please help with pre-lab questions.
Pre-Lab Questions: 1. A sample of 2-butanol has a specific rotation of +3.25. Determine the optical purity (%ee) and percent composition of this sample (see Mohrig section 17.4). The specific rotation of pure (+)-2-butanol is +13.0°. 2. The equation for the formation of the diastereomeric salts is shown in the background information (performed in Part A of the procedure). Write this chemical equation in your notebook, then ALSO write a balanced equation for the formation...
1. According to the paper, what does lactate dehydrogenase
(LDH) do and what does it allow to happen within the myofiber? (5
points)
2. According to the paper, what is the major disadvantage of
relying on glycolysis during high-intensity exercise? (5
points)
3. Using Figure 1 in the paper, briefly describe the different
sources of ATP production at 50% versus 90% AND explain whether you
believe this depiction of ATP production applies to a Type IIX
myofiber in a human....
