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 (<br><br>"<br>" 2PCl3 ", and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (<br>" PCl3 + Cl2 "<br>" 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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the chemical equation and phenomenon of the reaction between phosphorus and sulfuric acid?
1. ** Reaction of Phosphorous and Dilute Sulfuric Acid ** - The chemical equation: Since diluted sulfuric acid is mainly acidic, phosphorus and diluted sulfuric acid do not undergo an oxido-reduction reaction. However, if the corresponding substance of phosphorus, such as phosphorous compound (Ca3P2 as an example), reacts with diluted sulfuric acid, the chemical equation is [Ca3P2 + 3H2SO4 (diluted)= 3CaSO4 + 2Ph3 →]. - [Phenomenon: Phosphine gas is generated during the reaction. Phosphine is a gas with the smell of garlic.] 2. ** Reaction of Phosphorous and Sulfuric Acid ** - The chemical equation was: [2P +5H2SO4 (concentrated)= 5SO2 ^+2H2O +2H3PO4]. - [Phenomenon: Sulfur dioxide gas with a pungent smell is generated during the reaction, and at the same time, phosphorous acid is generated.] Since the concentrated sulfuric acid had a strong oxidisation property, the phosphorus was oxided, and the reaction was violent and released a lot of heat. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the reaction of the equation for the slow fermentation of materials in the air?
The slow oxidization of materials in the air was an oxidization reaction. The oxygen reaction was a reaction in which a substance obtained oxygen. However, since the specific composition of the material was unknown, the specific equation for its slow fermentation in the air could not be given. If the material is iron, the equation for its slow decomposition in the air is: 4Fe3 = 2Fe2 = 2CuO; if it is copper, the equation is: 2Cu2 = 2CuO. The reaction equations of different materials depended on the types of reagents and reaction conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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>
Determination of Phosphorus in Flame Reaction
The flame reaction test for the determination of the potassium ion mainly had the following steps: First, the platinum wire was dipped in concentrated sulfuric acid and burned on a colorless flame until it was colorless. Then, the sample was dipped in the colorless flame and burned. Then, the color of the flame was observed through the blue Cobalt Glass. If the flame was purple, it meant that the sample contained the potassium ion. Otherwise, it did not. After the experiment, the platinum wire was dipped in concentrated sulfuric acid and burned until it was colorless. In the flame reaction, because the yellow color of the Na flame might cover up the color of the K flame, it had to be observed with blue Cobalt Glass. This method originated from Bunsen's experiment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Red Phosphorus and Isopropvl
The reaction of red phosphorus with potassium alcohol was a substitution reaction, and the reaction formula was CH3- CH(SH) -CH3 +I2(P)→ CH3-CHI-CH3 +HOI, where P13 was the catalyst. In addition, the red phosphorus was mixed evenly with the alcohol, placed in a ball mill tank, and ball-grinded under a protective atmosphere, then washed with alcohol and dried to obtain the ball-grinded red phosphorus. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
