Is the gas volume before and after the reaction equal to a irreversible reaction?
Based on the current information, I don't know what you want to ask about the irreversible reaction with the same gas volume before and after the reaction, such as the characteristics of the equilibrium movement, the judgment method, or other related concepts? If it was about the characteristics of the equilibrium shift, for a irreversible reaction with the same gas volume before and after the reaction (that is, the number of gas molecules does not change), changing the pressure, the concentration of the reacting gas and the generated gas will change to the same extent, but the concentration quotient will not change. The positive reaction and the reverse reaction rate will change to the same extent, but they will still be equal, and the equilibrium will not move. It should be noted that the above law is for reactions involving gases. Solid or liquid substances are less affected by pressure. When there is only solid or liquid substance in the equilibrium mixture, the pressure equilibrium generally does not move. If it's a question about other aspects, please clarify it so that you can answer it. Read more exciting novels for free
Is the rearranged reaction irreversible?
Whether or not the rearrange reaction was irreversible depended on the specific reaction type. For example, it was very difficult to develop an unsymmetrical multi-component 1,2 -rearrange reaction due to its complex reaction pathway and the reversibility that often accompanied it. This indicated that the multi-component 1,2-rearrange reaction might have reversibility. When the Y group and the XH group had similar negative ion stability, the Smiles rearrange was a reversibility reaction. The first few steps of the Ugi reaction were all reversibility. Some of the rearrangements were irreversible. For example, the reaction of an aromatic a-diketon to form an a-methylic acid under basic conditions was irreversible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the reaction method of Flue Gas Desulfurization?
The basic principle of Flue Gas Desulfurization is the acid and base neutralizing reaction. From the reaction methods, it could be divided into the following categories: 1. ** Wetting Flue Gas Desulfurization Technology **: It is a gas-liquid reaction with fast reaction speed, high efficiency, and high utilization rate of desulphurizer. 2. ** Dry Flue Gas Desulfurization Technology **: It is a gas-solid reaction. Compared to the wet Flue Gas Desulfurization System, the equipment is simple, the area occupied is small, the investment and operation cost are lower, the operation is convenient, the energy consumption is low, the product is easy to dispose of, and there is no sewage treatment system. However, the reaction speed is slow and the sulfur removal rate is low. 3. ** Semi-dry Flue Gas Desulfurization Technology **: Including spray drying method, semi-dry and semi-wet method, powder particle spouted bed Desulfurization, chimney spray Desulfurization, etc., combining some characteristics of wet and dry methods. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does the reaction phenomenon of the reaction between the soda ash and the non-metallic gas mean?
The reaction of soda with different non-metallic gases was different: - The reaction between carbon dioxide and carbon dioxide was as follows: 2NaOx + CO2 = Na2CO3 + H2O. There was no obvious experimental phenomenon in the reaction. - The reaction between the two was a disproportionate reaction, but no specific reaction phenomenon was mentioned. - The reaction between sulfur dioxide and sulfur dioxide was 2NaOx + SO2 = Na2SO3 + H2O, and the reaction phenomenon was not mentioned. - The reaction between sulfur dioxide and sulfur dioxide is 2NaOx + SO3 = Na2SO4 + H2O. The reaction phenomenon is not mentioned. - The reaction equation was Si +2NaOx + H2O = Na2SiO3 + 2H2. Gas was produced. However, it did not react with other non-metallic gases such as carbon dioxide and nitrogen dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There was no reaction at all when the gas water heater was ignited.
The reason why the gas water heater didn't fire was probably due to external factors and the water heater itself. External factors: 1. ** Power supply problem **: The gas water heater relies on the household 220V power supply to ensure the normal operation of the fan, electric control, ignition system, etc. The normal ignition work will be affected if the power socket is loose, the contact is poor, or the socket is tripped and the power is cut off. You can check if the power outlet or indicator light (if any) is normal. 2. ** Gas source problem **: When using piped gas, there may be insufficient gas and low gas supply pressure (gas supply pressure may be unstable during peak periods). When using liquefied gas tanks, you need to check the outlet pressure. Generally, it can only work normally when the pressure is around 2800Pa. If the pressure is too low or too high, the ignition will not work normally. 3. ** Water source problem **: The gas water heater has a function to prevent dry burning. Before ignition, a certain amount of water needs to pass through. If the water pressure of the water supply is low and cannot reach the starting water pressure, it will not be ignited. This could be caused by low tap water pressure, clogged water supply lines, incomplete valve opening, mixed water valve failure, and other factors. 4. ** Smoke exhaust environmental issues **: Force-exhaust gas water heater has a chimney. If it is blocked or strong wind flows into the chimney when it is used (such as corrosion and blockage due to years of disrepair or windy weather), for safety reasons, the water heater cannot ignite. Water heater malfunction: 1. ** Wind pressure switch malfunction **: The wind pressure switch of the forced exhaust gas water heater is used to detect whether the fan is operating normally to ensure that the air intake and exhaust gas discharge are normal. If the exhaust air volume cannot be accurately sensed, the electric control part will not start the ignition system. 2. ** Water flow sensor malfunction **: This sensor is used to sense the water flow through the water heater. If the scale affects its accurate sensing of water flow, it may not ignite. 3. ** Igniting System Failure **: The ignition system includes parts such as the ignition needle and the automatic flameout probe. If one of them is not working properly, such as the ignition needle not firing due to poor contact, the automatic flameout probe being dirty, etc., it will cause a non-firing failure. 4. ** Failure of the electronic control part **: Most modern gas water heater are electronic controlled, including various temperature sensors, temperature control systems, gas proportional valve control systems, circuit boards, etc. If there is a problem with one of the resistances or condensers, it may cause the fire to fail. However, the probability of this situation is relatively low. Once it occurs, most of the motherboards need to be replaced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation for preparing concentrated sulfuric acid and nitrogen gas
Based on context alone The concentrated sulfuric acid could not be used for the preparation of hydrogen. Because hydrogen is an basic gas, concentrated sulfuric acid is volatile and acidic. When the two meet, a reaction will occur: <anno data-annotation-id ="cdf10000 - 4c00 - 4c10 - 4c10-a100-a11111110000"></anno>(the reaction phenomenon is to produce a large amount of white smoke), rather than being used to prepare hydrogen. The laboratory usually uses a solid mixture of lithium monium and lithium monium to heat up to prepare hydrogen. The reaction equation is [2NH4] Cl2 + CaCl2][2][3][4][4][5][6][7][8][8][9][9][ CaCl_{2}+2H_{2}O + 2NH_{3}\uparrow\)。 <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction of the aluminum thermal reaction? Is it an exhalation reaction?
Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction of the rearrange reaction?
Rearrangement reaction refers to the migration of certain atoms or groups in the molecules of organic compounds under certain reaction conditions, resulting in the reorganization of the molecular structure. For example, the Beckmann Rearrangement Reaction was a reaction in which ketoximes were rearranged into N-substituted diamides under the action of an acidic catalyst; the Cope Rearrangement Reaction was a (3,3)-sigma-shift rearranging reaction of 1,5 -diene; the Hofmann-Martius Rearrangement Reaction was a reaction in which N-alkylated aromatic compounds were rearranged to the corresponding o-/p-alkylated aromatic compounds under the action of acid catalyst; the Curtius Rearrangement Reaction was a type of nuclopathic rearrangements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
