“Pocket Money Blues” is the title of the text you are going to read. Before you read, answer the questions: What kind of music is the blues — happy or sad? What do you think

2Al(OH)₃ = Al₂O₃ + 3H₂O
Al₂O₃ = 2Al + 1,5O₂ (электролиз)
2Al + 3Cl₂ = 2AlCl₃
AlCl₃ + 3NaOH = Al(OH)₃ + 3NaCl
Al(OH)₃ + KOH = K[Al(OH)₄]
3K[Al(OH)₄] + AlCl₃ (конц) = 4Al(OH)₃↓ + 3NaCl
4Mg + 10HNO₃(разб) = 4Mg(NO₃)₂ + N₂O↑ + 5H₂O
MgNO₂ - такого нет соединения
Mg + Cl₂ = MgCL₂
MgCl₂ + 2KOH = Mg(OH)₂ + 2KCl

2)Fe3O4+Al2O3=3Fe2O3+2Al
