7. Reina is making museum exhibits about two different rock types. How could energy have played a role in the different rock types forming?

Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.

Explanation:

Different sources of energy are required in the formation of rocks. A source of energy like the sun is vital in the facilitation of processes pertaining to rock formation that occur on the surface of the earth. Some of these processes include; erosion and weathering.

The internal heat energy from the earth also facilitate rock formation processes that occur at the core of the earth. Some of them include; melting and subduction. So, energy from different sources result to different types of rocks.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
