Hence, 5.1 * 10^-11 alpha particles is being emitted each second by the sample.

<h3>What is half life?</h3>

The term half life is the time taken for only half of the original  amount of radioactive nuclides to remain.

Thus, we have that the half life is 432.2 years or 1.36 * 10^10 s.

k = 0.693/ 1.36 * 10^10 s

k = 5.1 * 10^-11 alpha particles per second.

5. given the ratio of reactants, what is the possibility of obtaining di- and polychlorinated product? explain.
Vladimir79 [104]

The ratio of reactants is chlorination of <u>2,3</u> dimethyl butane the possibility of obtaining do and the polychlorinated product is not seen.

When a mixture of methane and chlorine is exposed to ultraviolet light a substitution reaction occurs and the organic product is chloromethane. Because there are various hydrogen atoms that can be extracted in the first propagation step.

Abstraction of a hydrogen atom from the middle carbon of propane results in 2-chloropropane. In the presence of sunlight, methane reacts with chlorine to form chloromethane. The chlorination of methane is a free radical substitution reaction. Chlorine cannot turn into free radicals in the dark, so no reaction takes place. Therefore, the presence of sunlight is essential for the reaction to proceed.
