<h3><u>Answer;</u></h3>

10 percent

<h3><u>Explanation;</u></h3>
  • Probability is a number that describes how likely it is that an event will occur.
  • In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
  • Therefore; as a percentage;

1/10 × 100 = 10 percent

  • Hence; The probability of each individual event occurring is 10 percent

What multiplicity would you expect in a 1h nmr spectrum for the indicated proton(s)? (1 pts)
Vedmedyk [2.9K]

Triplet multiplicity would expect in a 1h NMR spectrum for the indicated proton(s).

The spectrum is the invisible radio frequencies that radio signals pass through. These signals let you make phone calls from your mobile device, tag your friends on  call an Uber, and get directions to your destination, all from your mobile device.

Spectrum management is the art and science of managing the use of the radio spectrum to minimize interference and ensure that the radio spectrum is used in the most efficient manner possible for the public good. For USDOT, this focuses on supporting safe, efficient, and economical transportation. Spectrum Networks is a suite of news and sports networks owned and operated by Charter Communications, Inc.

The half-life of the carbon 14 isotope is 5730 years. If there were 4 billion atoms of C-14 in a particular organism at the time
Lina20 [59]

Answer:

1 billion

Explanation:

The computation of the number of atoms for C-14 is shown below:

Because it is mentioned

Half the isotope for carbon 14 is 5,730 years

Currently if there had been 4 billion it would equate to 2 billion

Now that the 2 billion would've been 1 billion in the next 5,730 years

And it'll become 3 half-life

Therefore the number of C-14 atoms is 1 billion
