Answer: A solid compound in a sealed container is a covalent compound because it has a low melting point.
Explanation:
Ionic compounds have strong electrostatic forces which are strong in nature and cannot be broken down at low temperature.
Whereas covalent compounds have Vanderwaal forces which are weak in nature. Therefore, covalent compounds melts at low temperature.
Thus, it can be concluded that a solid compound in a sealed container is a covalent compound because it has a low melting point.

b. decrease in the number of neutrons in the nucleus of an atom
c. increase in the number of neutrons in the nucleus of an atom
d. change in the number of protons in a nucleus of an atom
Answer: Option (d) is the correct answer.
Explanation:
Transmutation is a process which brings changes in the nucleus occur because of change in the number of protons of an atom. Therefore, the atom formed will have different properties from its parent atom.
For example,
A transmutation can be natural or artificial in nature.
Thus, we can conclude that a transmutation reaction must always involve a change in the number of protons in a nucleus of an atom.
