Different metals had different reaction conditions with oxygen: 1. For active metals such as Na, they could react with oxygen at room temperature. However, the reaction at room temperature was relatively slow, and the reaction was intense when ignited. 2. For example, more active metals such as aluminum and aluminum could react with oxygen at room temperature, and the reaction was relatively easy to carry out. 3. The reaction between iron and oxygen required heating or ignition. 4. The reaction between copper and oxygen required heating. 5. It was difficult for metals like gold to react with oxygen. In addition, the reaction condition between titanium and oxygen was high temperature heating. In short, the mobility of the metal could be judged by the difficulty of the reaction between the metal and oxygen or the intensity of the reaction phenomenon under the same conditions.

1. ** Reaction conditions of metals and acid ** - In the sequence of metal activity, the metal in front of hydrogen can replace the hydrogen in the acid to form hydrogen. - The acid in the reagent could not be an oxiding acid such as HNO3 or concentrated H2SO4. 2. ** Reaction conditions of metals and alkalium **: Generally, active metals (such as aluminum) react with alkalium, such as the reaction of aluminum with a solution of soda. During the reaction, the aluminum must have a certain chemical activity, and the concentration of the alkalium solution must reach a certain concentration (reaction equation: <<2A1>+<2H2O>>=<2NaAlO2>+<3H2O>>>). However, the reaction of common metals with alkalium is relatively rare compared to the reaction of metals with acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between hydrogen and oxygen required ignition. From a microscopic point of view, the reaction involved a change at the molecular level. Every two hydrogen molecules and one oxygen molecules would react to form two water molecules under ignition conditions. In this reaction, 4 parts by mass of hydrogen reacted with 32 parts by mass of oxygen to form 36 parts by mass of water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the amount of oxygen is small, the reaction will produce sulfur and water. The reaction condition is ignition (ignition in pure oxygen), and the chemical equation is O2 + 2H2S == 2S +2H2O. When there is sufficient oxygen, the reaction will produce sulfur dioxide and water. The reaction condition is also ignition, and the chemical equation is 3O2 + 2H2S == 2SO2 + 2H2O. However, the reference materials did not mention the reaction of hydrogen sulfur with oxygen and water, so they could only give an explanation about the reaction conditions of hydrogen sulfur and oxygen. They could not accurately answer the question of "what are the reaction conditions of hydrogen sulfur, oxygen, and water?" <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between methane and sufficient oxygen was ignited to form water and carbon dioxide; carbon dioxide and nitrogen reacted under high temperature and high pressure to form carbolic acid and water; the reaction between oxygen and nitrogen was not mentioned in the reference materials; carbon dioxide and water reacted under the effect of titanium (normal temperature and pressure) to form substances such as methane, methanoi, and formated acid, not with oxygen. Therefore, based on the available information, it could be confirmed that the reaction between methane and oxygen was the ignition condition, and the reaction between carbon dioxide and hydrogen was under high temperature and high pressure. The reaction conditions for oxygen and hydrogen could not be accurately given. <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>
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>

Chloration reaction conditions: - Hot chloridizing: Heat energy is used to stimulate Cl2 to generate a free radical of chloridize, which then reacts with the carbon molecules to form a chloride-containing compound. In the industrial thermal chloridizing process, the ratio of Cl2/CH2 is 1:3 - 4, and the main products are CH Cl2 and CH2 Cl2. Too much Cl2 is easy to explode. The reaction mechanism is a free radical chain reaction, and the composition of the product is related to temperature. - Photo-chloration: Light (commonly used as a light source) is used to excite Cl2 to generate a free radical of Cl2, which then reacts with a hydrogen atom to form a chloride-containing compound. The process is carried out in a liquid phase under mild reaction conditions. - The method of chloridizing by using a catalyst was divided into two types, namely, the uniform and the non-uniform ones. For example, some reactions required high temperature, high pressure, and a catalyst. The ore chloridizing reaction required high temperature, high pressure, and a catalyst. The reaction products were metal chloride-like and hydrogen chloride-like gases. The reaction principle was that the metal elements would undergo an oxido-reduction reaction with the hydrogen. Some organic compounds needed iron and other catalyst for the chloridizing reaction. For example, in the presence of iron catalyst, hydrogen was replaced by chloridize to form chloridize. - For the chloridizing reaction of a specific substance, for example, the preparation of the chloridizing reaction. Oxidation reaction conditions: - [Ores are usually oxided under normal temperature and pressure. The speed and degree of oxidisation are affected by factors such as temperature, humidity, and oxygen concentration. It usually occurs on the surface of ores, causing changes in physical properties such as color, hardness, and density.] - For the thermal reaction of DCl2 in a hydrogen/oxygen mixture, the reaction was carried out in a tube-flow reactor according to the basic thermochemical principles, and the thermal cracking reaction was also studied in the tube-flow reactor. - For the reactions related to propene, it was necessary to prevent local high temperatures and high local Cl2 concentration. Among the reactions of the unsaturation, there were reactions such as the production of 1,2 -diclorethlene from ethene, and the synthesis of ethyne into ethene. The purpose of the oxification of ethene was to utilize the use of the Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
