Question

hoàn thành sơ đồ phản ơngs sau giúp em với

Al -> Al2 -> AlCl3 -> Al (OH)3 -> Al2 (SO4)3

Answer 1

\(\left(1\right)4Al+3O_2\rightarrow2Al_2O_3\)
\(\left(2\right)Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)
\(\left(3\right)AlCl_3+3NaOH\rightarrow Al\left(OH\right)_3+3NaCl\)
\(\left(4\right)2Al\left(OH\right)_3+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+6H_2O\)

Answer 2

4Al+ 3O₂\(\xrightarrow[]{to}\) 2Al₂O₃

Al₂O₃+ 6HCl\(\rightarrow\) 2AlCl₃+ 3H₂O

AlCl₃+ 3NaOH\(\rightarrow\) Al(OH)₃\(\downarrow\)+ 3NaCl

2Al(OH)₃+ 3H₂SO₄\(\rightarrow\) Al₂(SO₄)₃+ 6H₂O

Answer 3

4Al + 3O2-t0--> 2Al2O3

Al2O3 + 6HCl--> 2AlCl3 + h2O

AlCl3 + 3NaOH---> Al(OH)3 + 3NaCl

Al(OH)3 + 3H2SO4--> Al2(SO4)3 +3 H2O
