The Reaction of Aluminium-Sulphate and Sodium-Sulphate
The double decomposition reaction between aluminum and sulfur could produce aluminum sulfuric acid, which was called NaAlSO4·12H2O. The reaction formula was: the reaction between aluminum and sulfur could produce aluminum sulfuric acid, which was called aluminum sulfuric acid. It was a colorless cubic octagonal crystal or white crystalline powder with a density of 1.6754 g/cubic centimeter. It was easily dissolved in water but not in alcohol. It was easily weathered in the air and lost 12 crystals of water when heated to become an anhydrite. It was widely used as a buffer, neutralizing agent, and solidifying agent in the food industry. It could also be used for refining sugar, as a raw material for swelling agents, and as a water purifying agent.

The equation of the reaction between Barium Sulphate and Alkaline Sulphate
BaSO4 does not react with NaOx, so there is no chemical reaction equation. Both of them did not have the conditions for metathesis and oxido-reduction reactions.

Barrett Limit Test
"We can conclude that the Barrett sniper rifle has shown its powerful power and bulletproof ability in the extreme test. According to the test results, Barrett's ammunition could penetrate steel plates that were more than 20 millimeters thick. Even at a distance of 500 meters, it could still penetrate steel plates that were 15 millimeters thick. In addition, the Barrett's bullets were made of metal and could easily penetrate simple bulletproof vests and ordinary brick walls. The Barrett sniper rifle was known as the "King of Heavy Sniping", and it displayed an astonishing deterrent force on the battlefield. Its main use was an anti-material rifle that could destroy high-value targets such as light armored vehicles, radars, ammunition dumps, and aircraft. In addition, the Barrett had an ultra-long range and extremely high accuracy. The maximum accurate range was 1850 meters and the maximum range was 2500 meters.

Reaction of Iron in Copper Sulphate
When the iron reacted with the copper sulfuric acid solution, the iron could replace the copper from the copper sulfuric acid because the iron was more active than the copper. The reaction equation was: FeSO2 = FeSO2 + Cu2, and the reaction phenomenon was that a red solid was separated from the iron surface.

The Reaction of Sodium Sulphate and Permanganate
There was no reaction between the two. What happened between salt and salt was a double decomposition reaction, and the product should be two new kinds of salt. However, in order for the double decomposition reaction to occur, at least one of the two new salt should be a deposit. If the reaction between the salt and the salt occurred, the resulting salt and salt would be dissolved, so the two would not react.

Reaction of Sulfur Sulphate with Iodine
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.

What does it mean to test the reaction limit?
The limit of a chemical reaction was to study the maximum degree that a irreversible reaction could achieve under certain conditions, which was the dynamic equilibrium of a chemical reaction. Testing the reaction limit might be a way to determine whether a irreversible reaction had reached the maximum level (chemical equilibrium).
In a state of chemical equilibrium, there were some characteristics that could be used as a basis for testing. For example, the positive reaction rate and the reverse reaction rate were equal; the concentration of each component in the reaction mixture remained unchanged, including the concentration, mass fraction, and mass fraction of the substance; for the irreversible reaction that was completely participated by gas and the change of the front and back stoichiometries, the pressure and the average relative molecular weight remained unchanged; For the same substance, the amount of substance that breaks the chemical bond is equal to the amount of substance that forms the chemical bond. Through the detection or observation of these relevant indicators, it could be determined whether the reaction had reached the reaction limit.

The difference between lead cement and calcium sulphate
Barium Sulphate cement and lead cement were two different materials. They were different in composition and characteristics. Barium sulfuric acid cement was mainly composed of raw materials such as sulfuric acid, cement grog, and plaster, while lead cement was mainly composed of lead and cement. Barium Sulphate cement was commonly used in radiation protection projects, such as nuclear reactor shielding and hospital X-ray room buildings, while lead cement was not considered suitable for shielding projects due to its volatile nature and toxicity. In addition, the proportion of the barium-based cement was higher, with a relative density of 4.5, while the density of the lead cement was lower. However, the specific differences and applications of these two materials needed further research and understanding.

Reaction Formula of Besium Hydride and Alkaline Sulphate
The reaction equation between BeOx and NaOx was: Be(Ox) 2 + 2NaOx = Na 2 BeO 2 + 2H 2 O. Besium hydrogen was an amphoric hydrogen dioxide, which could react with both strong acid and strong base, so it could react with the above reaction.
