Прошу направить меня в решении задания 9 класса: - al = al2s3 = al(oh)3 = al2(so4)3

Как я понял нужно составить цепочку превращений, так что лови: 1. Реакция соединения алюминия с расплавленной серой в отсутствие кислорода и влаги: 2Al + 3S --> Al2S3 2. Al2S3 + 6H2O --> 2Al(OH)3 + 3H2S↑ 3. 2Al(OH)3 + 3H2SO4 --> Al2(SO4)3 + 6 H2O

These are four different chemical compounds with different chemical formulas and properties. - Al is the chemical symbol for aluminum, a metallic element with atomic number 13. - Al2S3 is aluminum sulfide, a compound composed of two aluminum atoms and three sulfur atoms. It is a white or grayish powder that is used in the production of other chemicals. - Al(OH)3 is aluminum hydroxide, a compound that forms a gel-like substance when mixed with water. It is commonly used in antacids and as a coagulant in water treatment. - Al2(SO4)3 is aluminum sulfate, a compound composed of two aluminum atoms and three sulfate ions. It is used in the production of paper, as a flocculant in water treatment, and as a mordant in dyeing textiles.
