When sulfur reacted with metals, it was weakly oxidiser (weaker than oxygen and sulfur), forming low-cost metal sulphides. For example, iron and sulfur react to form iron dioxide (FeS → FeS), which is black and is not dissolved in water but can be dissolved in diluted acid; Copper and sulfur react to form copper dioxide (2CuS → CuS), which is also black and is neither dissolved in water nor diluted acid; Mercury and sulfur react to form mercury dioxide (Mercury + S → HgS), which is also black and can be used to deal with scattered mercury droplets. In terms of application, the reaction of mercury and sulfur to form mercury sulfur could be used to deal with scattered mercury droplets and prevent mercury from evaporating and causing harm.

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>
The main types of metal-to-metal reactions were displacement reactions, reduction reactions, oxidization reactions, and so on. A substitution reaction is a reaction in which one metal atom substitutes for another metal atom. For example, such a reaction can occur between iron and copper. The reduction reaction was a reaction in which metal atoms lost their electrons, like the reaction between sulfur and sulfur. An oxidization reaction was a reaction in which metal atoms gained electrons, such as the reaction between iron and oxygen. Metal-to-metal reactions could produce metallic compounds. This reaction usually required specific conditions, such as high temperature, high pressure, and a catalyst. The reaction type also included chemical reactions. In terms of practical applications, metal-metal reactions could be used for alloy preparation, smelting metal, welding (connecting broken metals through reaction), surface treatment (forming a protective film on the metal surface to improve corrosion resistance), and manufacturing catalyst (accelerating chemical reaction rate). Moreover, in the metal activity order table, the metal ranked at the front could react with the metal ranked at the back. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
The reaction of the reaction between the two metals was as follows: Mn + H ^SO2 = Mn ^SO2 + H ^^; the reaction of the reaction between the two metals was as follows: Mn + 2 ^H ^SO2 = Mn ^SO2 + 2 ^H ^O + Mn ^. If there is an excessive amount of copper, it will first occur as: Mn +2H ^SO2 (concentrated)= Mn ^SO2 + Mn ^O, and then as: Mn + H ^SO2 (diluted)= Mn ^SO2 + Mn ^O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
During the reaction between the two, the original color of the solution would fade. Before the reaction, the solution may be purplish-black (elemental iodines are purplish-black crystals). Due to the oxidisation of iodines, it will undergo an oxido-reduction reaction with the reducing sodium-thionate (I <2>+2Na <2> S <2> O <2>= 2NaI+Na <2> S <2> O <2>). During the reaction, the iodines will be reduced, and the color of the solution will gradually fade until it disappears. If the solution was purplish-red due to air before the reaction, the purplish-red color would fade after the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The chemical equation for the reaction between sulfur and oxygen is: S + O2 SO_2\)。 The reaction phenomenon was: burning in the air to produce a light blue flame, releasing heat and producing a gas with a pungent smell; burning in oxygen to produce a bright blue-purple flame, releasing heat and producing a gas with a pungent smell. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
