Viết PTHH thực hiện sơ đồ sau:

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

b) \(Ca\underrightarrow{\left(1\right)}CaO\underrightarrow{\left(2\right)}Ca\left(OH\right)_2\underrightarrow{\left(3\right)}CaCo_3\underrightarrow{\left(4\right)}H_2\)

Cảm ơn ạ.

viết PTHH hoàn thành dãy biến hóa sau(ghi rõ đkpứ nếu có)
