Viết phương trình hóa học hoàn thành sơ đồ chuyển hóa sau ( ghi rõ điều kiện nếu có)

        FeO\(\underrightarrow{\left(1\right)}\)FeSO₄\(\underrightarrow{\left(2\right)}\)Fe(OH)₂\(\underrightarrow{\left(3\right)}\)FeO\(\underrightarrow{\left(4\right)}\)FeCl₂.

HELP ME!!!MAI MIK THI RỒI!

Hoàn thành sơ đồ chuyển hóa :

S  \(\underrightarrow{\left(1\right)}\) SO₂ \(\underrightarrow{\left(2\right)}\) H₂SO₃ \(\underrightarrow{\left(3\right)}\) Na₂SO₃ \(\underrightarrow{\left(4\right)}\) SO₂  \(\underrightarrow{\left(5\right)}\) Na₂SO₃

_{Mọi người ơi giúp mk với}

Viết PTHH thực hiện sơ đồ sau:

a) \(KMnO_4\underrightarrow{\left(1\right)}O_2\underrightarrow{\left(2\right)}SO_2\underrightarrow{\left(3\right)}SO_3\underrightarrow{\left(4\right)}H_2SO_4\underrightarrow{\left(5\right)}Al_{2_{ }}\left(SO_4\right)_3\)
