Sio2 and sf6 reaction equation
When SiO2 was etched, if the process was performed by using the SiF6, the reaction process could be expressed as: SiF6 + e--SiF5 + F (free radical) +2e, SiO2 + 4F--SiF4 (gas) + O
Reaction equation of NaF and SiO2
2NaF + H₂SiO₃ = Na₂SiO₃ + 2HF↑。However, it was important to note that sulfuric acid was a weak acid. When this reaction occurred in a solution, if the sulfuric acid was in a precipitative state, the reaction might be difficult to carry out. <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>

multistep reaction rate equation
For multi-step reactions (complex reactions), the reaction rate equation could not be simply written according to the total reaction equation. Complex reactions were composed of multiple elementary reactions (reactions that could be completed after a single collision). In the elementary reaction, there is a strict quantitative relationship between the reaction rate and the concentration of the reagent. It follows the law of mass action, that is, at a constant temperature, the rate of the elementary reaction is proportional to the product of the power of the concentration of the reagent. The power index is equal to the Stoichiometer number in the reaction equation. The general form of the rate equation is: (v = kc^{a}(A)c^{b}(B)(where k is the rate constant, c(A) and c(B) are the concentration of the reagents, and a and b are the measurements in the reaction equation). However, for multi-step reactions, the rate of the entire reaction was usually determined by the slowest elementary reaction step. For example, the reaction mechanism of a complex reaction was: a)<X + Y> Z>(fast reaction);b)<Z + W> Q>(slow reaction, speed determining step). Then the rate equation of this complex reaction mainly depended on the rate equation of speed determining step b, the reaction rate <x>(v = kc(Z)c(W)>. If the concentration of the intermediate product <Z>> could be expressed by the reagents <X>,<Y>>, then the reaction rate equation expressed by the original reagents could be obtained. In short, the multi-step reaction rate equation needed to be determined by analyzing the reaction mechanism, determining the rate-determining step, and then combining the characteristics of each elementary reaction step and the relationship between the concentration of the reagents and the intermediate products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of diesel and oxygen
Dieselfuel is a complex mixture, its main component is a carbon dioxide (CnH2n +2, etc.). The chemical equation of its combustion reaction is: CnH2n +2+(3n +1)/2O2 → nCO2 +(n + 1)H2O. However, in actual diesel combustion, due to the air composition (including N2, O2, etc.) and different combustion conditions, the combustion products include carbon dioxide and water, carbon dioxide (produced when there is no oxygen), carbon dioxide (produced when incomplete combustion), nitrogen dioxide (produced when high temperature and oxygen are rich), sulfur dioxide (produced when diesel contains sulfur), etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
