Question

Xác định số oxi hóa của các nguyên tố trong các chất: N₂, NH₃, NH₄Cl, NaNO₃  , H₂S, S, H₂SO₃, H₂SO₄, SO₂, SO₃  , HCl, HClO, NaClO₃, HClO₄

Answer 1

\(N_2:N\left(0\right)\)

\(NH_3:H\left(+1\right);N\left(-3\right)\)

\(NH_4Cl:H\left(+1\right);Cl\left(-1\right);N\left(-3\right)\)

\(NaNO_3:O\left(-2\right);Na\left(+1\right);N\left(+5\right)\)

\(H_2S:H\left(+1\right);S\left(-2\right)\)

\(S:S\left(0\right)\)

\(H_2SO_3:H\left(+1\right);O\left(-2\right);S\left(+4\right)\)

\(H_2SO_4:H\left(+1\right);S\left(+6\right);O\left(-2\right)\)

\(SO_2:O\left(-2\right);S\left(+4\right)\)

\(SO_3:O\left(-2\right);S\left(+6\right)\)

\(HCl:H\left(+1\right);Cl\left(-1\right)\)

\(HClO:H\left(+1\right);O\left(-2\right);Cl\left(+1\right)\)

\(NaClO_3:Na\left(+1\right);O\left(-2\right);Cl\left(+5\right)\)

\(HClO_4:O\left(-2\right);H\left(+1\right);Cl\left(+7\right)\)
