Chlorine, 2Al+3Cl2 == 2AlCl3 hydrochloric acid, 2Al+6HCl == 2AlCl3 + 3H2 zinc chloride, 2Al+3ZnCl2 == 3Zn +2AlCl3 2 2al photo generation; Combustion in oxygen, 4Al+3O2 = 2Al2O3, and the conditions are ignited; according to the stoichiometric ratio of each substance in the chemical reaction equation, which is the ratio of the amount of the substance, analysis 2Al+2NaOH+2H2O = 2NaAlO2 + 3H222Al ~ 3H2 It can be seen that 01 mol of Al produces a maximum of 015mol of hydrogen. Under standard conditions, the volume of 015mol of hydrogen is 013mol*224Lmol=336L.
1 According to the query on the official website of the game, first open the game account and enter the game. 2 Secondly, dress up the character. You can unlock beautiful clothes to dress up the character. 3 Finally, you can interact with the cute catwoman in the game. The catwoman will give different feedback to the player; Some Al and F can form a series of complexes. The most famous ones are cryolite and hexafluorosodium aluminate, with the chemical formula Na3AlF6. In addition, Al and F can also directly form AlF3 and aluminum trifluoride. For a detailed introduction of the two substances, see aluminum trifluoride htm cryolite htm; the chemical equation for aluminum oxidation in air is 4Al +3O? = 2Al?O?Specific explanation is as follows: reactant 4Al represents 4 aluminum atoms, 3O? Represents three oxygen molecule product 2Al? O?Represents the reaction process of two aluminum oxide molecules. At room temperature, pure aluminum combines with oxygen in the air. After chemical reaction, the aluminum oxide oxide layer is protected and the aluminum oxide layer will adhere to the surface of the aluminum, hindering the oxygen from interacting with the internal; The software used to generate videos mainly includes Adobe Premiere Final Cut Pro and Adobe Premiere is a widely used professional video editing software that provides a wealth of editing sound color correction and special effects tools for professional film and television production and personal video creation.al photo generationHis software compatibility is good. Final Cut Pro is a video editing software developed by Apple. It is mainly used on the Mac platform and is powerful; 1 When the solution reacts with Al to form Al3 +, the solution is acidic. NO3 and OH are removed from the anions, and finally only SO42 is left. Barium sulfate is a precipitate at this time. Remove, and silver sulfate is slightly soluble in water. If it exists, silver can be separated out. Remove copper sulfate and it is blue. Remove, only magnesium 2 is left. When the solution reacts with Al to form AlO2, the solution is alkaline. The essence of the reaction between aluminum and alkali is that aluminum reacts with water first and reacts; 1. The solution that can react with Al to form a large amount of hydrogen is acid or base. Na+K+NO3+ will not react with H+ or OH to form a gas precipitate or water, so it can coexist. 2. The Ag+AgOH that forms the precipitate is unstable and quickly turns into Ag2OCa2 + Note that it is a slightly soluble Mg2 + Fe2 + white precipitate, which is easy to be oxidized and quickly turns into gray-green and finally turns into a red-brown precipitate, that is, FeOH3Fe3 + red-brown precipitate; Knowledge point analysis of compounds that aluminum can react with alkali to form metaaluminate. The common reaction is that aluminum reacts with strong basic sodium hydroxide NaOH or potassium hydroxide KOH to form metaaluminate ion. The reaction equation is as follows: 2Al + 2NaOH +6H2O2NaAlOH4 + 3H2 In this reaction, aluminum reacts with hydroxide to form metaaluminate ion NaAlOH4, which simultaneously releases hydrogen. Knowledge point application 1; Why can the reaction between Al and NaOH solution produce "hydrogen"? The metal in front of the metal's active surface hydrogen, that is, the metal on the left can react with water to replace hydrogen to obtain hydroxide and hydrogen. However, because some hydroxides are insoluble in water, they will be wrapped around the metal and prevent the reaction from proceeding further. That is, common metals such as iron, aluminum and zinc cannot react with water to release hydrogen, but some metal hydroxides can react with strong bases, so these metals; Among the choices of AI software, which one is easy to use often depends on the specific application scenarios and personal needs. Currently, there are a number of excellent AI software on the market, which perform well in their respective fields. For text generation and dialogue communication, 147GPT is a highly regarded tool. It not only has strong language understanding and generation capabilities, but also supports multiple languages and can be applied to multiple scenarios such as content creation, copywriting, data analysis and report generation.
Al reacts with strong base solution to form AlO2, 2Al+2NaOH+2H2O = 2NaAlO2 + 3H2. Generally, Al cannot directly form aluminum hydroxide. It usually reacts with acid first to form Al3 +, and then reacts with weak base or appropriate amount of strong base to form aluminum hydroxide. However, the oxygen absorption corrosion of Al is 4Al+3O2 + 6H2O = 4AlOH3.
The specific reaction process of aluminum and sulfuric acid to form aluminum sulfate and hydrogen is as follows: Reaction type of reactant aluminum Al and sulfuric acid H #8322SO #8324 This is a displacement reaction, in which aluminum displaces hydrogen ions in sulfuric acid to produce hydrogen products aluminum sulfate Al #8322SO #8324 #8323 and hydrogen H #8322 Reaction characteristics The reaction between strong acid and metal Sulfuric acid is a strong acid.
