Ion equation and phenomenon summary of sulfur and metal reaction
For the reaction between sulfur and metal, the following are the common reactions and situations: - Sulfur and iron reaction: The chemical equation is: FeS + S = (heating)FeS. This reaction does not involve free moving ions, so it cannot be rewritten as an ion equation. The phenomenon was the formation of black solid iron Sulphide. - Sulfur and copper reaction: The chemical equation is 2Cu + S = (heating) Cu2 S. Similarly, the ion equation cannot be written. The phenomenon was the formation of black cuprous sulfur solid. - Sulfur and Na reaction: The chemical equation is 2Na + S =(grinding)Na <2> S. There is no need to rewrite the ion equation. The phenomenon was that during the grinding process, a violent reaction formed a white solid of sulfur dioxide. - Sulfur and aluminum reaction: The chemical equation is 3S +2AI = Al2S, which cannot be rewritten as an ion equation. The reaction phenomenon was the formation of aluminum sulfur solid. - Sulfur and mercury reaction: The chemical equation is as follows: Mercury + S = HgS, which cannot be written as an ion equation. The reaction phenomenon is the formation of black mercury sulfur solid. In general, since most of these reactions were solid-state reactions or did not carry out the ionisation process in the solution system, there was basically no ion equation. Most of the reaction phenomena were the formation of the corresponding sulfur solid, and the color of the solid was different. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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 ^->,<SO3 ^{2 -}+ O2 + Ox ^-→ 2SO4 ^{2 -}+ H2O>. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation and phenomenon summary of sulfur dioxide and sulfuric acid
Sulfur dioxide ($SO2 $) and sulfuric acid ($H2SO4 $) had different reactions. If it was concentrated sulfuric acid, the reaction equation was: 2H2SO4 (concentrated)+ SO2 = 2H2O +3SO3. The phenomenon was that the pungent gas ($SO2 $) was absorbed by concentrated sulfuric acid, and a small amount of smoke might be seen during the reaction ($SO3 $might form acid mist in the air). If it was diluted sulfuric acid, it would basically not react. He could simply draw a picture with the reaction equation written on it and a small picture beside it to indicate the phenomenon of smoke production. <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>
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>
Reaction equation and phenomenon analysis of sulfur dioxide and acidic bichromic acid
以硫酸为例，二氧化硫与酸性重铬酸钾反应的化学方程式为：\(K_{2}Cr_{2}O_{7}+3SO_{2}+H_{2}SO_{4} = K_{2}SO_{4}+Cr_{2}(SO_{4})_{3}+H_{2}O\)，其离子方程式为：\(Cr_{2}O_{7}^{2 - }+3SO_{2}+2H^{+}=3SO_{4}^{2 - }+2Cr^{3 + }+H_{2}O\)。 在这个反应中，重铬酸钾（\(K_{2}Cr_{2}O_{7}\)）中的铬元素从 +6价被还原为 +3价的\(Cr^{3 + }\)，而二氧化硫（\(SO_{2}\)）被氧化为硫酸根离子（\(SO_{4}^{2 - }\)）。反应现象方面，溶液的颜色会发生变化，由于重铬酸根离子（\(Cr_{2}O_{7}^{2 - }\)）通常具有特定颜色（一般为橙红色），反应后生成的\(Cr^{3 + }\)离子具有不同颜色（一般为绿色），所以反应过程中可以观察到溶液颜色由橙红色转变为绿色。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
