There are many natural phenomena in the nature in which we live.
Among them, light and water are two indispensable substances in our lives, light can shine on the earth, and can photosynthesize plants in nature.
Water is the source of human lifeIn fact, light and water can react, which is related to physical phenomena as wellChemical reactionsIt has a lot to do with it, so let's analyze it in detail.
We all know that light and water are a necessity for human life that exists in our natural society and can bring many benefits to our lives. In our social life, in fact, light and water can react. For example, water is originally a colorless and odorless liquid, just like the water in the sea is called seawater, and the water we usually use at home looks colorless and odorless, but it looks blue in the sea, or in the large rivers with a wide basin, the water also has a color.
This is the result of the interaction between light and water, we all know that there are several colored rays such as red, yellow, blue, green, indigo and purple in the atmosphere, this kind of light is generally rarely seen, only when there is rainy weather on a sunny day, we will see the phenomenon of rainbows in the sky, and it is very rare to see rainbows, in which colored rays are gathered together to form a beautiful rainbow bridge.
Another phenomenon is that when we put chopsticks in a cup filled with water, and look at the chopsticks in the cup under the condition of light, we will feel as if the chopsticks have been broken, which is the refraction of light. The above is my summary of some of the phenomena of the reaction of light and water, in addition to these, of course, there are many more, in fact, there are a lot of phenomena in our life that react with light, if you observe carefully, you will find that there is a lot of fun, so people say that the world is not lacking in each, but lacks a pair of eyes to find beauty, so we should observe life more.

Under certain conditions, light can react with water to decompose hydrogen and oxygen. Photosplitting water is the first source of oxygen in the early earth's atmosphere, and it is also an important direction for modern human beings to develop clean energy.
-
Light can react with water under certain conditions to decompose hydrogen and oxygen. Photosplitting water was the first of oxygen in the earth's atmosphere in the early days, and it is now an important symbol of human development of clean energy.

Solution: Note: Under acidic and neutral conditions, phosgene does not react with water, and under alkaline conditions, CoCl2+4NaOH = 2NaCl+2H2O+Na2CO3.
-
Phosgene: also known as carbonyl chloride colorless gas. Poisonous. Slightly soluble in water and gradually hydrolyzed. The hydrolysate is a chemical reaction.
-
coCl2+H2O==2HCl+CO2, give your teacher a junior high school chemistry textbook, and then he will start all over again.
-
Phosgene can be hydrolyzed when exposed to water to form HCl and CO2
cocl2 + h2o = 2hcl + co2
-
It should be able to react and produce CO2 and HCl
-
phosgene is hydrolyzed when exposed to water to produce two acids (hydrochloric acid and carbonic acid); Carbonic acid is unstable and decomposes to form carbon dioxide and water.
-
coCl2+H2O=2HCl+CO2, it seems that the chemistry teacher is going to be unlucky.
-
If the experimental conditions are complete, light and water can indeed produce chemical reactions. We all know that in the environment of the solar system, we are often blessed by the sun, and sometimes, under the strong exposure of the sun, the insufficient amount of water will be evaporated by the heat of the sun, so if in the laboratory, the scientific personnel are well equipped under the condition that the water and light will react under this premise.
In the chemical equation, we look at the chemical elements they contain, which will decompose or fuse under certain conditions to regenerate new chemical elements;
First of all, if you put an alkaline substance under alkaline conditions in a laboratory using equipment, the chemical reaction equation between light and water is approximately as follows
cocl2+4naoh=2nacl+2h2o+na2co3
Secondly, under acidic conditions, it does not react, so we skip it and enter the next reaction situation "hydrolysis", the light itself will also react after encountering water, which is phosgene hydrolysis, and finally "HCl" and "CO2" will be generated, and the reaction reaction equation is this:
cocl2+h2o=2hcl+co2
Finally, it should be explained that in fact, light and water can also have chemical reactions in the absence of external forces, for example, when light hits the surface of the water, the following gases will be produced immediately, about CO2, NO2, SO2, Cl2 and so on;
In industry, in the manufacturing industry, the principle of chemical reaction between light and water will be used to hydrolyze to produce metals such as Na, K, and Ca, while non-metallic solids will also produce CaO, Na202, C and so on.
Therefore, in general, the chemical reactants produced by light and water are far more than these, so these equations are of great help in chemical laboratory subjects, industry and life.
-
It can work. In daily life, strong sunlight exposure, like water evaporation, is actually a reaction of chemical action. Hydrolysis reactions occur under acidic conditions.
-
If the experimental conditions are complete, light and water can indeed produce a chemical reaction. We all know that in the environment of the solar system, we are often blessed by the sun. Sometimes, in strong sunlight, the insufficient water is evaporated by the sun's heat.
Therefore, in the laboratory, if there is enough scientific personnel equipment, water and light will react to a certain extent under this premise.
-
There are no known experiments in which light reacts directly with water.
However, in high school biology textbooks, photosynthesis in plants is introduced, and light is one of the conditions for the synthesis of organic matter.
-
The precursor to photosynthesis is the purification process of plants, algae and certain bacteria, under the irradiation of visible light, through light reaction and dark reaction, using photosynthetic pigments to convert carbon dioxide and water into organic matter and release oxygen.
CO2+H2O is used by light energy and chloroplasts to produce CH2O (organic matter) and O2
Deuterium, deuterium, tritium and tritium are all atoms, this reaction cannot be controlled at present, it can only be used as a **, hydrogen bomb is. This is nuclear fusion. >>>More
Fluorine is the most reactive non-metallic element. Fluorine and hydrogen energy are easily combined to form hydrofluoric acid. Fluorine can react with almost all elements, hydrofluoric acid inherits its properties, and also has a strong corrosiveness, and can react with most metals and non-metals. >>>More

1. Sea level rise.
Climate warming may increase a small amount of precipitation in northern China, but it may not be able to withstand evaporation consumption, and the serious water shortage situation will be difficult to alleviate, and the drought in the north will continue to fluctuate and expand, and the increase in the frequency and intensity of drought will aggravate grassland soil erosion, thus increasing the trend of desertification infiltration. Global warming causes the oceans to thermally expand and glaciers to melt, causing sea levels to rise. >>>More
White radish is a common vegetable, which can be eaten raw or cooked, and its taste is slightly spicy. Modern research believes that white radish contains mustard oil, amylase and crude fiber, which has the effects of promoting digestion, enhancing appetite, speeding up gastrointestinal peristalsis, and relieving cough and phlegm. The theory of traditional Chinese medicine also believes that the taste is sweet and spicy, cool, enters the lung and stomach meridians, and is a good food therapy, which can ** or assist ** a variety of diseases, and the Compendium of Materia Medica calls it "the most beneficial among vegetables". >>>More
