Question

you are given with
(a)iron nails (b)cuso4 solution (c)bacl2 (d)cu powder
(e)ferrrous sulphate crystals (f)quick lime
make five reactions that can take place from these materials

Answer 1

Hy

Fe + CuSO4= FeSO4 +Cu
CuSO4 + bacl2 = BaSO4 + CuCl2
Cao + FeSO4 = CaSO4 + Fe2O3
CaO + CuSO4= CaSO4 + CuO
BaSO4 + CaO= BaO+ Ca(SO4)2

Hope this helps u. :)

Answer 2

(a) Reaction of iron nails:

When iron reacts with water and oxygen to form rust.

4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃

(b) Reaction of CuSO₄ solution:

When iron reacts with iron and copper sulfate, we get iron sulfate.

Fe + CuSO₄ → FeSO₄ + Cu

(c) Reaction of BaCl₂:

When barium chloride reacts with sodium sulfate, we get barium sulfate and sodium chloride.

BaCl₂ + Na₂SO₄ = BaSO₄ + NaCl

(d) Reaction of Cu powder :

When copper power reacts with oxygen to form copper(II) oxide(black).

2Cu + O₂ → 2CuO

(e) Reaction of ferrous sulfate crystals:

When ferrous sulfate is heated, it produces ferric oxide, sulfur dioxide and sulfur trioxide.

2FeSO₄ → Fe₂O₃ + SO₂ + SO₃

(f) Reaction of quick lime:

The quick lime reacts with water to form slaked lime.

CaO + 2H₂O — Ca(OH)₂ + H₂
