The solar nebula was (a) rock and metal.

The solar system has evolved significantly since its birth. Many moons formed from disks of gas and dust orbiting their parent planets, while others are thought to have formed independently and later been captured by their planets. Moreover, like Earth's Moon, it could also be the result of a giant impact. Collisions between celestial bodies continue to occur to this day and are central to the evolution of the solar system. Due to gravitational interactions, the planets may be misaligned [2]. It is now believed that this planetary migration was responsible for much of the early development of the solar system. Known as the

Nebula Hypothesis, this model was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Subsequent developments have interwoven various scientific disciplines, including astronomy, chemistry, geology, physics and planetary science. Since the dawn of the space age in the 1950s and the discovery of exoplanets in the 1990s, models have been challenged and refined to explain new observations.

The solar nebula was a disk-shaped cloud of gas and dust composed of rock and metal particles, hydrogen compounds (such as water, methane, and ammonia), and a mixture of hydrogen and helium. This mixture of materials is what eventually coalesced to form the sun, planets, and other objects in the solar system.

The chemistry underlying the disinfection of water by chlorination involves the use of chlorine to oxidize and kill pathogens in the water.

Chlorine is the active agent in the destruction of the pathogens, and it works by breaking up the cell walls of the bacteria and other microorganisms.

The practical sources of the active ingredient include chlorine gas, hypochlorite, and chlorine dioxide.

Chlorine gas is usually produced in a laboratory and is then added to the water. Hypochlorite is a salt that can be added to the water, while chlorine dioxide is a gas that is typically applied in the form of tablets or powder.

Chlorination is a process used to disinfect water by adding chlorine or a chlorine-containing compound, such as sodium hypochlorite or calcium hypochlorite. Chlorine is a powerful oxidant, which reacts with the organic materials in the water, such as proteins, carbohydrates, and fats, to form compounds that are toxic to many bacteria and viruses. The active agent in the destruction of the pathogens is the chlorine.

The practical sources of the active ingredient are chlorine gas, sodium and calcium hypochlorite. Chlorine gas is the most common form used for disinfecting water and is typically used in larger municipal water systems. It is released into the water as a gas and quickly breaks down into free chlorine, which is the active disinfectant. Sodium and calcium hypochlorite are chlorine compounds that are in a liquid or solid form. They are used in smaller water systems and require the addition of other chemicals to make them effective disinfectants.

When chlorine is added to water, it reacts with the water molecules to form hypochlorous acid (HOCl) and hypochlorite ion (ClO-). The hypochlorous acid is the active disinfectant that kills or inactivates the microorganisms in the water.

It is a strong oxidizing agent and reacts with the proteins and cell walls of the microorganisms, destroying them. The hypochlorite ion is a weaker oxidizing agent and is responsible for the long-term disinfection of the water. It reacts with the organic material in the water to form compounds that are toxic to microorganisms.
