C. low boiling points, since convalent bonds are comprise of two non metal elements, the have relatively low boiling points, since most of them are gases.
<u>Answer:</u> The nuclear equations for the given process is written below.
<u>Explanation:</u>
The chemical equation for the bombardment of neutron to U-238 isotope follows:

Beta decay is defined as the process in which neutrons get converted into an electron and a proton. The released electron is known as the beta particle.

The chemical equation for the first beta decay process of
follows:

The chemical equation for the second beta decay process of
follows:

Hence, the nuclear equations for the given process is written above.
53.6 hectometers is not equal to 0.536 kilometer
The postulate of Dalton's atomic theory which is a result of the law of conservation of mass is: Atoms are indivisible particles, which can neither be created nor destroyed in a chemical reaction.
