Question

Na-NaOH-Al(OH)3-Al2O3-AlCl3-Al(NO3)3

Answer 1

1) $2Na + 2H_{2}O = 2NaOH + H_{2}$
2) $AlCl_{3} + 3NaOH = Al(OH)_{3} + 3NaCl$
3) $2Al(OH)_{3} = Al_{2}O_{3} + 3H_{2}O$
4) $Al_{2}O_{3} + 6HCl = 2AlCl_{3} + 3H_{2}O$
5) $AlCl_{3} + 3AgNO_{3} = 3AgCl + Al(NO_{3})_{3}$

Answer 2

А можно еще электронный баланс?
