Answer:

I am the one who you just got a 100 points from from the 100 Point giveaway. I guess I gave away all my points except for one, so I need more points so I hope you don't mind if I am writing this, because you won't get another person to answer. Sorry!

(+)-Carvone and (-)-carvone differ in the orientations of the substituents around which of the following carbon atoms?
myrzilka [38]

Answer:

The correct option is: B. Carbon 5 only

Explanation:

Carvone is a naturally-occurring monoterpenoid consisting of a six-membered cyclic ring. <u>The </u><u><em>carbon-5</em></u><u> of this cyclic ring of Carvone is </u><u><em>chiral, </em></u><u>due to which Carvone exhibits </u><u><em>enantiomerism</em></u><u>.</u>

The two <em>enantiomeric forms</em> of Carvone are: R-(–)-carvone, or L-carvone, and S-(+)-carvone, or D-carvone.

<em><u>These two enantiomeric forms differ in the orientation of the substituents on the chiral carbon-5.</u></em>

<u />

<u>Therefore, the correct option is B. Carbon 5 only.</u>

For the first order process: AB The half-life of A is 62.1 seconds. If a sample of A initially has 250.0 g, what mass (in g) of
Molodets [167]

<u>Answer:</u> The mass of sample A after given time is 99.05 g.

<u>Explanation:</u>

All the radioactive reactions follows first order kinetics.

The equation used to calculate half life for first order kinetics:

t_{1/2}=\frac{0.693}{k}

We are given:

t_{1/2}=62.1s

Putting values in above equation, we get:

k=\frac{0.693}{62.1}=0.011s^{-1}

Rate law expression for first order kinetics is given by the equation:

k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}

where,

k = rate constant = 0.011s^{-1}

t = time taken for decay process = 84.2 s

[A_o] = initial amount of the reactant = 250 g

[A] = amount left after decay process =  ?

Putting values in above equation, we get:

0.011s^{-1}=\frac{2.303}{84.2s}\log\frac{250}{[A]}

[A]=99.05g

Hence, the mass of sample A after given time is 99.05 g.
