Radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

<h3>What is radiation?</h3>

Radiation refers to the transmission of energy by means of subatomic particles that travel as waves.

Radioactive isotopes are also known as radioisotopes, which have unstable combinations of subatomic particles (i.e., neutrons or protons) in their atomic nuclei, and thus may emit alpha particles, gamma rays or beta particles.

Radioactive isotopes such as C14 lost (emit) energy per unit of time, which is known as radiation or radioactive decay.

In conclusion, radiation decrease over time due to the concentration of radioactive atoms and the concentration decreases as radioactive particles are emitted (Option D).

A certain hydrocarbon has a molecular formula of C9H16. Which of the following is not a structural possibility for this hydrocar
snow_tiger [21]

Answer: Option (d) is the correct answer.

Explanation:

It is given that molecular formula is C_{9}H_{16}. Now, we will calculate the degree of unsaturation as follows.

Degree of unsaturation = C_{n} - \frac{\text{monovalent}}{2} + \frac{\text{trivalent}}{2} + 1

                                  = 9 - \frac{16}{2} + 1

                                  = 9 - 8 + 1

                                  = 2

As the degree of unsaturation comes out to be 2. It means that this compound will contain one ring and one double bond.

Yes, this compound could be an alkyne as for alkyne D.B.E = 2.

But this compound cannot be a cycloalkane because for a cycloalkane D.B.E = 1 which is due to the ring only.

Thus, we can conclude that it is a cycloalkane is not a structural possibility for this hydrocarbon.

The correct response would be 3. The alkaline earth metals would tend to lose its valence electrons, in this case 2 of them at different energy levels, to form the same respective ion, which is +2.
