Write the reaction equation: Al-AlCl3-Al (NO3) 3-Al (OH) 3-Al2O3-NaAlO2

1) 2Al + 3Cl2 = 2AlCl3 (when aluminum interacts with chlorine, aluminum chloride is formed);

2) AlCl3 + 3AgNO3 = Al (NO3) 3 + 3AgCl3 (when aluminum chloride interacts with silver nitrate, aluminum nitrate and silver chloride are formed);

3) Al (NO3) 3 + 3NaOH = Al (OH) 3 + 3NaNO3 (when aluminum nitrate interacts with sodium hydroxide, aluminum hydroxide and sodium nitrate are formed);

4) 2Al (OH) 3 = Al2O3 + 3H2O (when heated, aluminum hydroxide decomposes into aluminum oxide and water);

5) Al2O3 + Na2CO3 = 2NaAlO2 + CO2 (when aluminum oxide interacts with sodium carbonate, sodium aluminate and carbon dioxide are formed).
