Water is H2O, why can t it be synthesized?

Water can be miscible with glycerin in any ratio, and insoluble with petroleum products such as gasoline and diesel; and vegetable oil insoluble.

Water molecules are polar molecules that have a strong electromagnetic attraction towards each other. The molecules of oil are non-polar and have low electromagnetism, making it difficult to diffuse into water, just as non-magnetic objects are difficult to be adsorbed by magnets. So it's hard for the two to be miscible with each other.

Oil, the original meaning is also water, so it is called oil water. Posterior finger extract. The oil does not dissolve in water, which is caused by the difference in surface tension, the surface tension of oil is small, and the water is large, so it is not compatible. The surface tension of alcohol is close to that of water, so it can melt and can be blended in any proportion.

Additional Description: Oil. A general term for a hydrophobic substance that is liquid at room temperature.

It is composed of one or more liquid hydrocarbons (a large part of silicone oil is composed of silicons), and is distinguished from hydrocarbons such as alcohols, ketones and ethers in that the components of the oil are not polarized. The difference with fats is the molecular length of the compounds that make up the oil and the connections between the molecules, comparing its number of chains.

The principle of similarity and dissolution.

"Similar" means that the solute is structurally similar to the solvent; "Soluble" means that solutes and solvents are miscible with each other. For example, there are strong hydrogen bonds between water molecules, and water molecules can not only provide hydrogen atoms for the formation of hydrogen bonds, but also accept hydrogen atoms provided by other molecules because there are lone pairs of electrons on the oxygen atoms, and hydrogen bonds are the main binding force between water molecules. Therefore, any solute molecule that provides hydrogen or accepts hydrogen for the formation of hydrogen bonds is "structurally similar" to water

Such as RoH (alcohol), RCOOH (carboxylic acid), R2C=O (ketone), RconH2 (amide), etc., can be combined with water through hydrogen bonding, and have considerable solubility in water. Of course, the structure and size of the R group in the above substances also have an effect on the solubility in water. Such as alcohol:

R—OH, with the increase of the R group, the non-polar part of the molecule increases, so that the structural difference with water (polar molecule) increases, so the solubility in water also gradually decreases.

For gases and solid solutes, "similar dissolving" also applies. For a class of gases with similar structures, the higher the boiling point, the greater the intermolecular forces, the closer it is to the liquid, and therefore the greater the solubility in the liquid. For example, the boiling point of O2 (90 K) is higher than the boiling point of H2 (20 K), so the solubility of O2 in water is greater than that of H2.

For a class of solid solutes with similar structures, the lower their melting point, the smaller their intermolecular forces, the closer they are to liquids, and therefore the greater their solubility in liquids.

Answer: Because the number of outermost electrons of the hydrogen atom is only 1, it is possible to lose only 1 electron; The number of electrons in the outermost shell of the oxygen atom is 6, so that 2 electric sliders can be obtained. Therefore, an oxygen atom must obtain two electrons from two hydrogen atoms, so it becomes a water molecule H2O

The chemical formula of water liquid slag is H2O, which is composed of hydrogen element and oxygen element slag, and a water molecule contains two hydrogen atoms and one oxygen atom.

If it's H2I, it's water.

Nowadays, many businesses like to fool people and rush to Yu Gao, and change the tomb to play with nouns. For example, hydrogen-rich diffuse water, nano, graphene, ......

Hi, I'm a water molecule and I've lived for hundreds of millions of years. From the day two hydrogen atoms and one oxygen atom combined, I was born – H2O.

However, for a long time, people thought that my molecular formula was oh, which was really depressing (just think, if it is a stick, how can it be combined to become a liquid!?). So, my molecular formula should be H2O.

What is the bond angle of h-o-h, don't know the "bond angle"? Then now you take three balls and line them up in the word "Pin".'shape, the top one is called "o", and the bottom two are called "h"; Take two more wires, connect O-H, and the bond angle is Hoh. o-h bond length centimeter (hey, do you have to drink more than one of our brothers in one gulp?)

But even if you drink me, I won't die. I am a three-molecule whole, and I will not disappear easily unless I bombard my molecular chain with high energy and break it, and I will be "dismembered"; This is the stability of all molecular chains.

Of course, we come together in three forms. They are gaseous (water vapor), liquid (water), solid (ice). When we are gaseous, we can run around each other and move at the speed of sound; Unfortunately though, we always crash @ @在固态 and we are fixed by force to regular crystals (imprisoned?).

Curiously, though, the density of ice is slightly less than that of water. Unexpected, isn't it?

My molecular formula is H2O – two H's and one O's. They join together and become friends – but not always in nature. O2 – two oxygen molecules – combine together to become oxygen.

H2 – two hydrogen molecules – combine together to become hydrogen. O2 is the source of life, and you humans cannot survive without oxygen. H2 can be burned, please use with caution.

But H2O - I can't burn, only a kind of "combustible ice" guy can. It's mixed with methane, and it's an outlier that doesn't look like a tooth.

Speaking of water, there is a guy called "mercury" who also gets on the edge of the water. But it's not a good guy! Its molecular formula is Hg – not an "H" molecule and a "G" molecule, but an "HG" molecule (mercury)! It has a strong toxic effect on the human body, please be careful!

One more thing to declare, don't call all liquids "water"; The molecular formula of water is H2O, and other liquids may not match us in any way. Let's say, sulfuric acid is also a liquid, but if you drink it, hehe......

Don't gossip too much, or people will get bored. Hehe, I'm going to your body, see you tomorrow!

The composition of water is hydrogen and oxygen, so water can be formed by the reaction of hydrogen-containing substances with oxygen-containing substances, such as hydrogen combustion, hydrogen and copper oxide reaction, etc

Synthetic water is certainly possible!! The simplest thing is to have hydrogen combustion (i.e. react with oxygen) to produce water!

The main reasons why water is not synthesized to treat water scarcity in arid areas are as follows:

The cost of synthetic water is high, and if hydrogen is burned to produce water, it will first need to consume a high cost to produce hydrogen, which requires a lot of energy costs and is not cost-effective.

The evaporation of water in arid areas is large, and the speed and amount of synthetic water may be difficult to achieve to solve the drought situation and be evaporated, without the effect of becoming an oasis, even if there is a little effect, the cost is very high, and it is difficult for any country to afford it!

The equation of CO2, H2O and Na2O2 reaction is tricky for many students, and it is basically written by rote memorization, but the good times are short-lived, and they will soon forget! So what to do? Teacher Qianlong created an original method to share with dear students, welcome students to be serious!

1. Water electrolysis 2H2O= energized = 2H2 + O2 2, react with metal elements 2Na+2H2O=2NaOH+H2 3, react with non-metallic elemental matter C+H2O= high temperature = CO+H24, react with metal oxides Cao + H2O === Ca(OH)25, react with non-metal oxides SO2 + H2O === H2SO3 SO3 + H2O === H2SO4

6. Reaction with salt CuSO4 + 5H2O ==== CuSO4 5H2O

and iron and magnesium at high temperatures. and sodium, sodium oxide, sodium peroxide. Can be hydrolyzed. It can be ,...... with CO2Forgot.

Water electrolysis produces hydrogen and oxygen.

2h20==energized====2h2 |+o2|There is a gas symbol.

It is a decomposition reaction.
