Question

Viết phương trình cân bằng của:

a) Fe + HNO₃-->Fe(NO₃)₃ + N_xO_y + H₂O

b) Mg + HNO₃-->Mg(NO₃)₂ + N_xO_y + H₂O

c) Fe_xO_y + H₂SO₄-->Fe₂(SO₄)₃ + SO₂ + H₂O

d) Fe_xO_y + HNO₃-->Fe(NO₃)₃ + NO₂ + H₂O

e) CrI₃ + Cl₂ + KOH-->K₂CrO₄ + KIO₄ + KCl + H₂O

f) Cu₂S + HNO_{3 loãng}-->NO + Cu(NO₃)₂ + CuSO₄ + H₂O

Answer 1

a)(5x-2y)Fe+(18x-6y)HNO₃--->(5x-2y)Fe(NO₃)₃+3N_xO_y+(9x-3y)H₂O

b)(5x-2y)Mg+(12x-4)HNO₃--->(5x-2y)Mg(NO₃)₂+2N_xO_y+(6x-2y)H₂O

c)2Fe_xO_y+(6x-2y)H₂SO₄--->xFe₂(SO₄)₃+(3x-2y)SO₂+(6x-2y)H₂O

d)Fe_xOy+(6x-2y)HNO₃--->xFe(NO₃)₃+(3x-2y)NO₂+(3x-y)H₂O

e)2Crl₃+27Cl₂+64KOH--->2K₂CrO₄+6KlO₄+54KCl+32H₂O

f)3Cu₂S+16HNO₃--->10NO+3Cu(NO₃)₂+3CuSO₄+8H₂O

Kiểm tra lại nhé!!!
