Because water is made up of hydrogen and oxygen, it can be produced by pressurizing hydrogen and oxygen. In natural water, the content of heavy water accounts for about that. Since the properties of deuterium and hydrogen differ very little, heavy water and ordinary water are also similar.
The ionic product constant of heavy water is.
The total concentration of metal ions such as calcium and magnesium in water is called hardness, and hard water has a great impact on production water such as boilers, so it should be softened and desalination. Hardness greater than 200mg l is usually called hard water.
Elemental analysis. Water (HO) is an inorganic substance composed of hydrogen and oxygen, which is a colorless and odorless transparent liquid at room temperature and pressure. Water is one of the most common substances, an important resource for the survival of all life, including humans, and the most important component of living organisms.
Water has played an important role in the evolution of life. Human beings have long begun to understand water, and water is regarded as a basic component in the ancient simple material concepts of the East and the West, and water is one of the five elements in ancient China. Water is also present in the ancient Western theory of the four elements.

Water is made up of hydrogen and oxygen, making water? This is too meaningless, however, hydrogen and oxygen can make water, put some soda ash in vinegar can also make water, if one day you are sad and cry, you will also "make" some water, but salt water is it. Huh

Water is made up of hydrogen and oxygen, and burning hydrogen produces water.
-
There are H and O in the water
2h2+o2=2h2o
There are also acid-base neutralization reactions, as well as some other reactions and so on, which produce water.

Water is so easy to make, but no one in the world has ever made water that way. Unless it's a madman.

more, such as the use of hydrogen peroxide.
-
2h2+o2=2h2o
There are also other chemical reactions that produce water, like acid-base neutralization.
hcl+naoh=nacl+h2o

Hydrogen is burned in oxygen.
Water is H2O
-
1 oxygen + 2 hydrogen = 1 water molecule.

Scientists have discovered that water is the best choice for humans!

Yes, artificial precipitation, also known as artificial precipitation, refers to the process of artificially supplementing the necessary conditions for the formation of precipitation according to the principle of precipitation formation in nature, and promoting the rapid condensation or collision and increase of cloud droplets into raindrops and falling to the ground.
The method is to choose the right time according to the physical characteristics of different clouds, and use airplanes and rockets to sow dry ice, silver iodide, salt powder and other catalysts into the clouds, so as to make the clouds precipitate or increase the amount of precipitation, so as to relieve or alleviate the drought of farmland, increase the irrigation water or water supply capacity of reservoirs, or increase the amount of water in the power generation period. China's earliest experiment with artificial rainfall was in 1958, when Jilin Province was hit by a drought not seen in 60 years.

A small amount of water can. But a lot of water can't, because making water is a dangerous process.
Water (H2O) is an inorganic substance composed of hydrogen and oxygen.
It may seem like a simple basic chemistry to be a colorless and odorless transparent liquid at room temperature and pressure, but making water is actually a very dangerous process.
To make water, oxygen and hydrogen must be combined, and the mixing of hydrogen and oxygen will cause a sudden**, ** will cause the individual hydrogen and oxygen molecules to combine to get water. Since both hydrogen and oxygen are extremely flammable, this "sudden**" is very dangerous and deadly.
The most famous airship in history "Hindenburg".
is a prime example of this. On May 6, 1937, the hydrogen-filled airship crossed the Atlantic.
During the voyage, the Hindenburg was burned into a fireball due to sparks caused by static electricity (or acts of sabotage), mixing hydrogen and oxygen**, and at least 23 of the 97 passengers and crew died.
Scientists speculate that if drinking water is to be created to sustain the global population, it will require an incredibly large hydrogen and oxygen mix** process. The method of making water was considered a crazy act a century ago (producing water by mixing hydrogen and oxygen to produce water), but as water resources become more and more scarce, how to convert hydrogen molecules and oxygen molecules into water has become the most attractive problem.

OK. Material: Hydrogen somewhat.
A bottle of oxygen. The fire is high and the chai is in the box.
Fang Yun Nianshan method: Mix hydrogen and oxygen and light it with a match.
Principle: 2H2+O2=2H2O Thank you!

OK. Isn't photosynthesis made by water!! Isn't it who ignites hydrogen and oxygen? Organic matter burning is not also water!

The structure of water. The water molecule (H2O) is made up of one oxygen atom and two hydrogen atoms. The relationship between these atoms gives water its unique electron polarity.
Water has an arrangement and a transformation; creation and re-creation; Seep foci permeate and dissolve any material it comes into contact with; and the unique ability to collect and store information wherever it goes, and through these abilities give their life force to all living beings.
Water molecules easily bind to other molecules. In other words, water is very "gregarious". It's very much desirable to mix with other ingredients and it's nice to take a "hitchhiker" with you.
If the water is loaded with good ingredients like nutrient-dense minerals and refreshing oxygen, that's a good thing; But if it brings toxic pollutants, dangerous chemicals, or disease-causing organisms into your bloodstream, that's bad!
According to this property, hydrogen and oxygen can be added to make water.

A few years ago, scientists demonstrated the phenomenon of light traveling at a speed of 17 m s, which is much lower than the breakaway speed of the Earth, which means that for a beam of 17 m s, the Earth is a black hole. >>>More
Pure water prepared by the distillation method. Distilled water can be divided into single and multiple times. After a distillation of water, the non-volatile components (salts) remain in the container and the volatile components (ammonia, carbon dioxide, organics) enter the initial fraction of the distilled water, usually only the middle part of the fraction is collected, which accounts for about 60. >>>More
