Submarines typically generate oxygen through a process called electrolysis. In this process, electricity is used to split water molecules into hydrogen and oxygen. The hydrogen is then vented overboard, while the oxygen is collected and stored for use by the crew. Some submarines also have systems that can scrub carbon dioxide from the air and […]

The anion (negatively charged ion) Cl is the anion (chloride ion). It is generated when the element chlorine (a halogen) gets an electron or when a molecule such as hydrogen chloride is dissolved in water or other polar solvents. Chloride compounds like sodium chloride are frequently extremely soluble in water. [4] It is an electrolyte
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth’s most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe.
The Sun is the central star of the Solar System. It is a nearly perfect ball of hot plasma that has been heated to incandescence by nuclear fusion processes in its center and radiates energy mostly as visible light, ultraviolet light, and infrared radiation. It is by far the most essential source of energy for
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth‘s hydrosphere and the fluids of all known living organisms. “Water” is the name of the liquid state of H2O at standard conditions for temperature and pressure. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula H2O, indicates that
A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei. Atomic number Symbol Name Phase at r.t. 1 H Hydrogen gas 2 He Helium gas 3 Li Lithium solid 4 Be Beryllium solid 5 B Boron solid 6 C Carbon solid 7 N Nitrogen gas 8
