b, ?+?-> BaCl2+H2O

c, CaCO3 + HCL -> ?+?

d,?+?->BaSO4+HCl

e, Fe(OH)₃+?->Fe2(SO4)₃+?

f, ?+?-> Al2(SO4)₃+ H2O

g, NaOH + HCl->?+?

h, Fe2O3+ H2SO4_(l)->?+?

i, Al+H2SO4_(l)->?+?

k, Cu+ H2SO4_(đ)-> ?+?

Answer 1

a, Fe + H₂SO₄ ->FeSO₄ + H₂

b, Ba(OH)₂ + 2HCl -> BaCl2+H2O

c, CaCO₃ +2 HCL -> CaCl₂ + H₂O + CO₂

d,BaCl₂ + H₂SO₄->BaSO₄+HCl

e, 2 Fe(OH)3+3 H₂SO₄->

f, 2Al(OH)₃ + 3H₂SO₄ -> Al₂(SO4)3+ 6 H₂O

g, NaOH + HCl -> NaCl + H₂O

h, Fe₂O₃+ 3 H₂SO₄(l)-> Fe₂(SO4)3 + 6H₂O

i, 2Al+3H₂SO₄(l)-> Al₂(SO4)3+ 3 H₂

k, Cu+ 2 H₂SO₄(đ)-> CuSO₄ + SO₂ + 2 H₂O

Answer 2

a, Fe + H2SO4 ->FeSO4 + H2

b, Ba(OH)2 + 2HCl -> BaCl2+H2O

c, CaCO3 +2 HCL -> CaCl2 + H2O + CO2

d,BaCl2 + H2SO4->BaSO4+HCl

f, 2Al(OH)3 + 3H2SO4 -> Al2(SO4)3+ 6 H2O

g, NaOH + HCl -> NaCl + H2O

h, Fe2O3+ 3 H2SO4(l)-> Fe2(SO4)3 + 6H2O

i, 2Al+3H2SO4(l)-> Al2(SO4)3+ 3 H2

k, Cu+ 2 H2SO4(đ)-> CuSO4 + SO2 + 2 H2O
