If (S)-glyceraldehyde has a specific rotation of -8.7°, what is the specific rotation of (R)- glyceraldehyde? A) -8.7° B) +8.7° C) 0.0° D) cannot be determined from the information given

Q: If (S)-glyceraldehyde has a specific rotation of -8.7°, what is the specific rotation of (R)- glyceraldehyde? A) -8.7° B) +8.7° C) 0.0° D) cannot be determined from the information given

Answer: B) +8.7° Explanation: The specific rotation of a chiral compound is a physical property that is characteristic of its stereochemistry. Enantiomers, which are mirror images of each other, have specific rotations that are equal in magnitude but opposite in sign. Since (S)-glyceraldehyde has a specific rotation of -8.7°, its enantiomer, (R)-glyceraldehyde, will have a specific rotation of +8.7°.

Answer: B) +8.7°

Which of the following statements is true? If more than one statement is true, identify all the statements which are true. [ 1 point for identifying all true statements, ‐ 0 . 5 points for choosing a wrong combination even if some of the statements chosen are true, 0 points for not answering ] ( i ) An all ‐ pass filter passes through all frequencies unchanged, but can change the phase of the signal ( ii ) If the FIR filter coefficients are symmetric, then it has linear phase ( iii ) FIR filter is computationally more efficient than an IIR filter of comparable performance ( iv ) A filter that does not operate in real ‐ time can be non ‐ causal

A game is said to be fair if the expected value (after considering the cost) is 0. This means that in the long run, both the player and the “house” would expect to win nothing. If the value is positive, the game is in your favor. If the value is negative, the game is not in your favor. At a carnival, you pay $1 to choose a card from a standard deck. If you choose a red card, you double your money, but if you pick a black card, you do not get any. (A standard deck of cards has 52 cards. 26 of the cards are red.)

Calculating tax incidence Suppose that the U.S. government decides to charge cola consumers a tax. Before the tax, 10,000 cases of cola were sold every week at a price of $5 per case. After the tax, 3,000 cases of cola are sold every week; consumers pay $8 per case (including the tax), and producers receive $3 per case. 1) The amount of the tax on a case of cola is $??? per case. 2) Of this amount, the burden that falls on consumers is $??? per case, and the burden that falls on producers is ???$ per case. 3) True or False: The effect of the tax on the quantity sold would have been the same as if the tax had been levied on producers.
