A sample of a uranium compound is found to be losing mass gradually. Explain what is happening to the sample.
irina [24]

Explanation:

Uranium have an unstable nuclei , hence it  is a radioactive element , and radioactive element can undergo radioactive decay like the alpha decay , beta decay .

Radioactive decay is a spontaneous breakdown of the atomic nucleus which , results in the release of energy along with radioactive particles , like alpha , beta , gamma etc .

Hence ,

The mass is lost from a sample of uranium .

Which of the following statements regarding spontaneous changes is false?A. Spontaneity is favored when heat is released.B. Spon
ArbitrLikvidat [17]

Answer: Option (E) is the correct answer.

Explanation:

A spontaneous reaction is defined as the process which tends to occur on its own. And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.

For example, ice melting at 25^{o}C is spontaneous primarily due to the increase in molecular disorder (dispersal of matter). Also, melting of ice is taking place on its own without any external force.

It is not necessary that all exothermic reactions will be exothermic in nature.

Thus, we can conclude that the statement all exothermic reactions are spontaneous, is false.
