Aluminum powder was mixed with iodine powder and a few drops of water were added. The substance obtained as a result of the violent reaction was dissolved in water and an excess of ammonia water was added. The separated precipitate was filtered off and calcined, and the calcination residue was fused with sodium carbonate. Write the equations of the four described reactions

4 reaction equations:
1) 2Al + 3I2 = 2AlI3
2) 3NH3 + 3H2O + AlI3 = Al (OH) 3 + 3NH4I
3) 2Al (OH) 3 = Al2O3 + 3H2O
4) Al2O3 + Na2CO3 = 2NaAlO2 + CO2
