What is the principle of the reaction between a hydrogen and a hydrogen?
The reaction mechanism between alkyls and halos was a substitution reaction of free radical. In the reaction, the halo (such as pure chorine, pure bromine, and not chorine water or bromine water) under the conditions of light/heat/free radical initiator, X-X was split into two X-free radical, X -and the HX-H on the alkyls formed hydrogen halo, and the alkyls left the alkyls free radical, which then reacted with X-X to form X -, and the cycle reaction could continue. The reaction between an aromatic compound (such as alkyne and alkyne) and a hydrogen atom was mainly an addition reaction. The double bond in an aromatic compound was a sigma-bond and a pi-bond. The pi-bond was more unstable and easy to break. The double bond opened to become a single bond, and the broken small half bond formed a covalent-bond with the hydrogen atom. In addition, the addition reaction of the hydrogen atom with the unsatured carbon could also be carried out. Aromatic compounds could only be substituted with a catalyst (such as iron trihalide, aluminum trihalide, iron powder, etc.), except for very active compounds (such as aromatic amine, vitamins, etc.). Fatty acid could only be substituted with a catalyst of red phosphorus, which generally produced an alpha substituted product.

If the reaction of hydrogen with hydrogen acid is below 25 degrees,
There were some problems with the reaction of hydrogen with sulfuric acid, even at temperatures below 25 degrees Celsius. Because the reaction between diluted sulfuric acid and zincate was an exothermic reaction, as the reaction progressed, the temperature of the reaction system would increase, and the volatile nature of the sulfuric acid would increase. As a result, the obtained hydrogen gas often contained hydrogen chloride-like gas and was not pure. Although diluted sulfuric acid could be used as a reagent to produce hydrogen, it had the drawback of impure hydrogen compared to diluted sulfuric acid. In addition, the reason why they didn't use concentrated sulfuric acid to produce hydrogen was because concentrated sulfuric acid was more volatile, and the hydrogen produced was more likely to be mixed with hydrogen chloride-like gas.

hydrogen airship
The hydrogen airship was a type of airship that used hydrogen as the filling gas.
At standard atmospheric pressure and 0 ° C, its density was 0.0899g/L. This characteristic allowed hydrogen to be used to fill airships to generate buoyancy to lift them off. However, hydrogen was flammable and not very safe. For example, in 1937, when the Hindeburg airship was about to land, the hydrogen had to be released. At that time, there was no wind, and the hydrogen could not be dispersed. It mixed with oxygen, and the static sparks caused by the contact between the cable and the ground caused an explosion. Moreover, the airship's outer shell was made of aluminum, which caused a thermal reaction that caused it to burn rapidly. After this accident, humans became more cautious in the choice of gas filling in airships. Modern airships were mostly filled with helium. However, hydrogen could be produced in a variety of ways, while helium was a rare gas that was difficult and expensive to produce.
The early airship development went through three eras of human-powered, steam-powered, and electric powered. It was used in the military field during World War I. In terms of origin, airships developed from hot air balloons. The first recorded hot air balloon appeared in 1783, and the first airship appeared in 1784. At the beginning of its birth, hydrogen airships were mainly used in the field of transportation. Now, with the development of technology and other factors, new airships (mostly non-hydrogen-filled) were widely used in transportation, aerial photography, remote sensing, advertising, and aerial exploration.

Mixed reaction of hydrogen peroxid and acidic hydrogen iodinate
The mixture of hydrogen peroxide-hydrogen peroxide-acid and hydrogen iodinate-acid would result in an oxido-reduction reaction. The reaction equation is [H2O2 + 2Hi]. In this reaction, the valency of the oxygen element in the hydrogen peroxid decreased from-1 to-2, showing its oxidisation, while the valency of the iodine-element in the hydrogen iodinate increased from-1 to 0, showing its reduction.

Can sulfur react with hydrogen dioxide to produce hydrogen?
No. The chemical equation of the reaction between sulfur and hydrogen dioxide is [3H_{2}O_{2}+S = H_{2} SO4_{4}+2H_2}O]. The reaction products are sulfuric acid and water, and no hydrogen is produced.

What are the reaction mechanisms of hydrogen production from hydrogen?
The reaction mechanism of hydrogen production from gasoline mainly had the following methods:
1. The steam reforming reaction (MPR) of the gasoline was one of the most common methods. The reaction equation is CH30H + H2O → CO2+ 3H2. In this reaction, the reaction between the alcohol and water vapor occurred under the effect of a catalyst to produce carbon dioxide and hydrogen. This reaction process was relatively complicated, involving the activation of the alcohol molecules, the breaking and reassembly of chemical bonds, and many other steps.
2. The reaction equation is CH30H + 1/2O2 → CO2+ 2H2. In this reaction, the partial oxidization of the oxygen and the alcohol produced carbon dioxide as well as hydrogen. The characteristic of this method was that the reaction speed was relatively fast, but the control of the reaction process was relatively difficult. It was necessary to accurately control the amount of oxygen supplied to avoid over-oxidization or incomplete reactions.
3. Alcohol autothermal reforming (ATR): It was a hydrogen production method that combined the steam reforming reaction and the partial oxidization reaction of the alcohol. The reaction equation can be roughly expressed as CH30H + xO2 +(1 - x)H2O → CO2+ (3 - 2x)H2. This method used the heat generated by the partial oxygen reaction to supply the steam reforming reaction, thus improving the energy utilization efficiency. It had certain advantages in practical applications.
