16 paź 2024 · water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances.
Water forms an extended network of hydrogen bonding interactions, with each water molecule capable of both creating and accepting two hydrogen bonds. As a result each and every water molecule in the liquid or solid state is surrounded by four hydrogen bonded neighbors.
The gaseous state of water is steam or water vapor. Water covers about 71% of the Earth's surface, with seas and oceans making up most of the water volume (about 96.5%). [23]
1 lip 2024 · Gaseous Water (Steam/Vapor) Water vapor, the gaseous form of water, is produced when water evaporates or boils. Steam is water in its gaseous state at temperatures above 100°C (212°F), where it becomes visible, like the steam from a boiling kettle.
17 sie 2024 · Water is the common name for dihydrogen monoxide or H 2 O. As for how to make water, the molecule is produced from numerous chemical reactions, including the synthesis reaction from its elements, hydrogen, and oxygen. The balanced chemical equation for the reaction is: 2 H 2 + O 2 → 2 H 2 O.
Structure of Water. Water is a simple molecule consisting of one oxygen atom bonded to two different hydrogen atoms. Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds). The oxygen atom attracts the shared electrons of the covalent bonds to a significantly greater extent than the hydrogen atoms.
How do two gases combine to make liquid water? Hydrogen and oxygen atoms are attracted by positive and negative charges which thwarts the random movement that would keep them as gases. Asked by: Arthur Newby, Liverpool.
