The reaction between Na and water was a violent chemical reaction, which was accompanied by phenomena such as heating up, deflagration, and light, which included the production of smoke. Based on the reaction principle, the outermost layer of the Na atom only had one electron, which was easy to lose. It had strong reduction properties and was very active. When Na comes into contact with water, the reaction equation is [2Na +2H2O = 2NaOx + H2O]. During the reaction process, the block would float on the surface of the water. Because the density of the block was lower than that of water, its buoyancy was greater than its own weight. The reaction between the two gases releases heat, melting the solid Na with a melting point of only 97.72°C into liquid Na, which forms a small ball due to surface tension. The volume of the steam released from the reaction rapidly expanded at a relatively high temperature and continuously hit the air, making a "hissing" sound. The water vapor generated in this process condensed into small droplets to form the so-called "smoke". At the same time, due to the high heat released by the reaction, it also accelerated the vaporizing of water, further promoting the production of smoke. Moreover, the exposed Na sphere would react with the air to form Na Chi O and a small amount of Na Chi O Chi. The latter would quickly react with H Chi O to form O Chi, and the generated H Chi and O Chi (including the O Chi in the air) would form an explosive gas mixture at a higher temperature within its explosive limit, resulting in a more intense reaction phenomenon. It seemed that the smoke would also be more obvious. Read more exciting novels for free
The pronunciation of the Dan word for "water Dan Xi Sheng Yan" was dàn or tán.
The black water coming out of a well in Jiangsu Province caused the villagers to be surprised and speculate. At first, the villagers thought that it was just sewage in the underground water, but then they found that they could not continue digging. Later on, they discovered that there were many holes at the bottom of the well, and black water was found in one of the holes. When the archaeologists arrived at the scene, they found that the nine imperial tombs of Sima Yi's descendants were buried in these caves. However, these tombs had long been looted by grave robbers, and there were very few burial artifacts left. This discovery aroused the excitement and surprise of the experts, revealing the thousand-year-old secret hidden in Chentan Village, Jiangsu Province.
When a small amount of sulfur dioxide is reacted with a small amount of sulfur dioxide, the reaction equation is: 2NaOx + SO2 = Na ^SO2 + H ^O. In this reaction, the reaction between the hydrogen dioxide and a small amount of sulfur dioxide formed a mixture of water and sulfur dioxide. Sulfur dioxide was a colorless, transparent gas with a pungent odor. When dissolved in water, it would form sulfurous acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There were many poems and sentences similar to the green clouds, the rain, the water, and the smoke. Below were some of the more famous ones: The mountain is not high, there is a fairy name; the water is not deep, there is a dragon spirit.

Of course, these sentences were just similar, and the specifics depended on one's personal preferences and preferences.

The fact that a chemical was easily dissolved in water did not mean that it would react with water. Solvency refers to the degree to which a substance can be dissolved in another substance. For some substances, they were easily dissolved in water because of the specific intermolecular forces between their molecules and water molecules. For example, the dissolution of an ion compound in water was the breaking of the ion bond under the action of water molecules, and the ion was surrounded by water molecules to form a hydrated ion. This process was a physical change. For example, the reason why salt was easy to dissolve in water was because of the static electricity between the salt ions and the water molecules, causing the salt crystals to disintegrate in the water and no new substances to be formed. When some substances came into contact with water, a chemical reaction would occur. The reaction product could be dissolved in water. This was a different concept from pure dissolution. During the reaction process, chemical bonds would break and form, and new substances would be formed. For example, carbon dioxide could be dissolved in water. Part of the carbon dioxide reacted with water to form carbolic acid, which was a chemical change. However, some of the carbon dioxide was only dispersed in water in the form of molecules, which was a physical solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
