The reaction of oxygen with sulfur
When oxygen meets sulfur, it will react and release a lot of heat. For example, when the reaction between hydrogen sulfureted and oxygen was small, it would produce sulfur and water. The chemical equation was [O2 + 2H2S = 2S +2H2O]. When the oxygen was excessive, it would produce sulfur dioxide and water. The chemical equation was [3O2 + 2H2S = 2SO2 + 2H2O]. Sulfides in the sulfurous waste water of oil refineries (usually in the form of Na salt or NH4) react with oxygen in the air as follows: <2HS^-+ O2 → SO4 ^{2 -}+ H2O>,<2S +2O2 + H2O → SO4 ^{2 -}+2Ox ^->,

The reaction of the sulfur dioxide and the water with the soda ash
When a small amount of sulfur dioxide is reacted with a small amount of sulfur dioxide, the reaction equation is: 2NaOx + SO2 = Na ^SO2 + H ^O. In this reaction, the reaction between the hydrogen dioxide and a small amount of sulfur dioxide formed a mixture of water and sulfur dioxide. Sulfur dioxide was a colorless, transparent gas with a pungent odor. When dissolved in water, it would form sulfurous acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation of aluminum and hydrogen and oxygen
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction between sulfur dioxide and potassium Permanganate?
The reaction between sulfur dioxide and potassium Permanganate was the fading of the solution. The chemical equation of the reaction is: 2KMNO2 + 5SO2 + 2H2O = 2MNO2 + 2H2SO2 + K2SO2. Because the reduction product of potassium Permanganate has almost no color, and the sulfuric acid of sulfur dioxide is colorless, it will cause the color of the solution to fade. The reaction was usually carried out under acidic conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to calculate the kinetic constant k of the oxygen reaction?
To determine the kinetic constant k of the reaction, the first step was to determine the rate equation of the reaction. The reaction rate equation could be summarized as a power product. The key to determining the rate equation was to determine the reaction order n, because the reaction order n reflected the degree of influence of concentration on the reaction rate and was the most important basis for speculating the reaction mechanism. The apparent rate constant k 'was a proportional constant that had nothing to do with concentration. At present, there were two main methods to determine the kinetic parameters (reaction order) of ozon: the integral method and the differential method. 1. Derivation method: Using the differential expression of the rate equation to determine the reaction order, the two sides of the rate equation differential expression are taken as the log, in v = Ink + nInC, and the reaction order n can be obtained through relevant data processing. 2. Calculating the reaction order by integration: This was a method to determine the reaction order by using the integration of the rate equation. It could also be divided into trial and error method and half-life method. The trial and error method was only suitable for integer-order reactions, while the half-life method required the calculation of the half-life of different initial concentration. After the reaction order n was determined, the kinetic constant k could be obtained by solving the formula for the reaction order m of the rate constant and the constant concentration of the component (this step was relatively simple). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
