[Giang Huong]

1, Al+O₂➝Al₂O32,K+O₂➞K₂O3,Al(OH)₃➞Al₂O₃+H₂O4,Al₂O₃+HCl➜AlCl₃+H₂O5,Al+HCl➜AlCl₃+H₂↑6,FeO+HCl➜FeCl₂+H₂O7,Fe₂O₃+H₂SO₄➜Fe₂(SO₄)₃+H₂O8,NaOH+H₂SO₄➜Na₂SO₄+H₂O9,Ca(OH)₂+FeCl₃->CaCl₂+Fe(OH)₃10,BaCl₂+H₂SO₄->BaSO₄↓+HCl

Answer 1

[𝓓𝓾𝔂 𝓐𝓷𝓱]

\(4Al+3O_2\underrightarrow{t^o}2Al_2O_3\)

\(4K+O_2\rightarrow2K_2O\)

\(2Al\left(OH\right)_3\underrightarrow{t^o}Al_2O_3+3H_2O\)

\(Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)

\(CaCl_2+Fe\left(OH\right)_3\rightarrow\) Không phản ứng

\(BaCl_2+H_2SO_4\rightarrow2HCl+BaSO_4\downarrow\)
