The following is a summary of the equations and phenomena of the reaction between sulfur and metals: 1. ** Sulfur and Iron Reaction ** - The equation is: FeS ${stack}{triangle}{=}=}$ FeS (Iron Sulphide, dark brown) - [Phenomenon: Iron powder and sulfur powder are mixed and heated to red heat. The reaction produces a black solid that releases a lot of heat.] 2. ** Sulfur and Copper Reaction ** - The equation: 2Cu + S $\stacking rel {\triangle}{=\!=}$ Copper Sulfur (black) - [Phenomenon: The reaction produces a black solid.] 3. ** Sulfur and mercury react ** - Formula: Mercury + S = HgS (Mercury Sulphide, black) - [Phenomenon: The reaction produces a black solid.] In general, when sulfur reacted with metals, sulfur showed its oxidisation, while metals showed its reduction. The reaction formed a black solid. Read more exciting novels for free

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>

Reaction of elemental sulfur and elemental sulfur

Under heating conditions, elemental sulfur and elemental sulfur can react violently and release a lot of heat. The reaction equation is: Mn + S = Mn (heating). The resulting Mn is a white or reddish-brown hexagonal crystal or powder. It can be dissolved in acid and phosphorus trichosphate. It will decompose in cold water to produce Mn (III) and Mn (III). It will decompose in hot water to produce Mn (III) and Mn (III). In cold and concentrated sulfuric acid, sulfur will be separated. In addition, when the combustion of sulfur dioxide was similar to the combustion of carbon dioxide, it would produce magnesium and elemental sulfur. However, the generated sulfur could continue to react with the combustion of sulfur to produce sulfur. The reaction condition was ignition. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
