Viết phương trình cân bằng của:
a) Fe + HNO3-->Fe(NO3)3 + NxOy + H2O
b) Mg + HNO3-->Mg(NO3)2 + NxOy + H2O
c) FexOy + H2SO4-->Fe2(SO4)3 + SO2 + H2O
d) FexOy + HNO3-->Fe(NO3)3 + NO2 + H2O
e) CrI3 + Cl2 + KOH-->K2CrO4 + KIO4 + KCl + H2O
f) Cu2S + HNO3 loãng-->NO + Cu(NO3)2 + CuSO4 + H2O
a)(5x-2y)Fe+(18x-6y)HNO3--->(5x-2y)Fe(NO3)3+3NxOy+(9x-3y)H2O
b)(5x-2y)Mg+(12x-4)HNO3--->(5x-2y)Mg(NO3)2+2NxOy+(6x-2y)H2O
c)2FexOy+(6x-2y)H2SO4--->xFe2(SO4)3+(3x-2y)SO2+(6x-2y)H2O
d)FexOy+(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
