Reaction equation of chloride-red phosphorus and explanation of phenomenon
The reaction between red phosphorus and Cl2 would result in two reactions. The first reaction is the reaction of red phosphorus with Cl2 to form phosphorous tri-(2P +3Cl2) [2PCl3], and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (
"
" 2PCl3 ", and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (
" PCl3 + Cl2 "
" stacking " Phosphorous pentachlorides was a white solid.
During the reaction process, the white solid particles of phosphorus pentachlorinate formed smoke, and the colorless liquid droplets of phosphorus tricolor formed fog, so the reaction phenomenon was white smoke.

Reaction equation phenomenon and explanation of the phenomenon of the reaction equation of the reaction of the reaction
There is no chemical reaction between NaCl2 and magnesiumcarbonate2. In chemistry, the conditions for metathesis reactions to occur were the formation of precipitations, gases, or water. After mixing the two, the conditions for the metathesis reaction were not met, so there was no reaction, no reaction equation, and no reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon of chloride-carbon dioxide
If the two did not react, the reaction equation could not be written. carbon dioxide (CO2) was a non-metallic oxide-like substance, while Cl2 was a non-metallic elemental substance. A substitution reaction occurred between the compound and the elemental substance. However, this kind of reaction required the compound to be a dissolved metal compound or acid, while CO2 was a non-metal compound, which did not meet the conditions, so the two did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and explanation of phenomenon of calcium carbonate-potassium chloride-calcium chloridereaction
There was no chemical reaction between the two. However, when the salt was added to the calcium dioxide, the dissolution of the calcium dioxide would increase. This was because of the salt effect. In the presence of a strong solute (such as calcium dioxide), the dissolution of some solute (such as calcium dioxide) would be greater than in water. This phenomenon of increasing the dissolution of the precipitations due to the addition of a strong solute was called the salt effect. It had to be distinguished from the same ion effect, which would reduce the dissolution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon of iron chloride-alcohol heating
The reaction between FeClCl2 and alcohol (C2H20H) under heating was more complicated, and it was generally believed that alcohol would be oxided by FeCl2. The reaction equation was: 6C H Oh + 4FeCl → 4Fe6CHCHO +12HQ +3H O (This reaction was only a possible reaction, and there may be many side reactions in the actual reaction). Phenomenon: The color of the solution may change because the iron chloride-based solution itself is brownish-yellow. Due to the formation of new substances during the reaction, the color may become lighter or other color changes may occur. If iron is formed, black solid substances may appear (but if the amount of iron formed is small, it may not be easy to observe). At the same time, there may be a pungent smell (because of the formation of substances such as Zhang). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the meaning of the reaction equation phenomenon of lead sulfuric acid and potassium chloride2?
The reaction between lead sulfuric acid and sulfuric acid could not produce precipitations, gases, and water, so the two could not react. There was no reaction equation or reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon explanation of hydrogen sulfureted, oxygen and water
When there was a small amount of oxygen, the chemical equation for the reaction between hydrogen sulfur and oxygen was: 2H2S + O2 = ignition = 2S +2H2O. The reaction phenomenon was that hydrogen hydrogen would burn in oxygen to produce a light yellow solid (sulfur), and at the same time, water would be produced. When there is an excess of oxygen, the chemical equation for the reaction between hydrogen sulfur and oxygen is: 2H2S +3O2 = ignition = 2SO2 + 2H2O. The reaction phenomenon was that hydrogen hydrogen would burn in oxygen to produce a pungent gas (sulfur dioxide) and water. The chemical equation for the reaction of hydrogen hydrogen, oxygen, and water was not found. Only the equation for the reaction of hydrogen hydrogen and oxygen (divided into two cases of small and excessive oxygen) was found. In these reactions, water was the reaction product rather than the reagent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction of heating metal mercury and the explanation and analysis of the phenomenon
Mercury reacts with oxygen under heating conditions to form mercury dioxide. The chemical equation is [2Mercury + O_{2}]{=[2Mercury + O_{2}]}{=[2Mercury + O_{2}]}{=[2Mercury + O_{2}}}}{=[2Mercury + O_{2}}}{=[2Mercury + O_{2}}}}{=[2Mercury + O_{2}}}{=[2O_{2}}}} 2HgO\)。 The reaction was the appearance of a large amount of white smoke. From the nature of the reaction, mercury was a chemical element with the element symbol <anno data-annotation-id ="00000000 - 4000 - 4000 - 8000 - 9000 - 80000000000"></anno>. It was located in the sixth cycle of the periodic table of chemical elements, Group III. It was a metal that existed in liquid form at room temperature and pressure. Its electron configuration allows the two electrons on the 6s sub-level to have extremely high orbital speeds, about 58% of the speed of light, which causes the mass of the electron to increase by 23% through the relativistic effect. The increase in the mass of the electron reduces the orbital radius, and mercury almost does not contribute its own electrons to form metal bonds. Mercury atoms attract each other mainly through van der Waals forces (this force is very weak). When heated, mercury reacted with oxygen to form mercury dioxide. Due to the change in the state of the substance during the reaction and the formation of the product, a large amount of white smoke appeared. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between potash and calcium chopstick and the explanation of the phenomenon
The reaction of K2CO3 and CaClO could produce CaCO3 and KClO. The chemical equation was: K2CO3 + CaClO = CaCO3 → 2KClO. Phenomenon explanation: White precipitations will appear during the reaction process. This is because calcium carbonite is a substance that is difficult to dissolve in water. It will be deposited in the form of precipitations in the solution. The resulting potassium hypochlorites are water-dissolved and exist in the form of ions in the solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
