Answer:
Stellar black holes form when the center of a very massive star collapses in upon itself.
C) After reacting, each ion has a stable octet.
Explanation:
When Na reacts with chlorine gas to form the ionic compound NaCl, after the reaction, each ion has a stable octet.
- The driving force for every reaction is the tendency of the atoms to have completely filled outer energy levels like the noble gases.
- To achieve this configuration, an atom may lose or gain or share electrons.
- In this way, their shells become completely filled and they attain stability.
- In the reaction between Na and Cl, Na, a metal loses an electron. Na then will have a configuration similar to that of Ne, a noble gas.
- The electron is then gained by the chlorine atom and it mimics an argon atom.

I would say the energy transformation that happens would be potential energy to kinetic energy. Potential energy is the energy possessed by an object when at rest. As you eat a meal, you store potential energy. As you move around, this energy is used and is transformed to the energy of motion which is the kinetic energy.
Liquids state than in the solid state because when it is solid the particals cant move as much than in the liquid state
