(a) Fe3O4 + H2 →Fe + H2O

(b) BaCl2+ Na2SO

4→BaSO4+NaCl

(c) Fe + CuSO4→FeSO4 + Cu

Write the type of reaction shown in (b) and (c) .​

Answer 1

Answer:

fe3o4 + 4H2 = 3fe + 4H2O

Explanation:

BaCl2 + Na2So4 = BaSo4 + 2NaCl

Fe+ CuSo4 = FeSo4 + cu

Answer 2

Answer:

those three are balanced equations
