Question

Cu(OH)-->CuO-->CuSO4

Answer 1

молекулярный вид:     
CuSO4 + NaOH = Cu(OH) (в осадке) + NaSO4
ионный вид:
Сu + + OH - = Cu(OH) (в осадке)
Cu(OH) = (при нагревании) = CuO + HOCuO + Ni = NiO + Cu

Answer 2

The series of chemical reactions you've mentioned involve the transformation of copper hydroxide (Cu(OH)2) into copper oxide (CuO) and then into copper sulfate (CuSO4). Let's break down each step:

1. Cu(OH)2 -> CuO: Copper hydroxide (Cu(OH)2) can be converted into copper oxide (CuO) through a dehydration reaction. When heated, copper hydroxide loses water molecules to form copper oxide:

   Cu(OH)2 -> CuO + H2O

   In this reaction, one molecule of copper hydroxide loses one molecule of water to become copper oxide.

2. CuO -> CuSO4: To convert copper oxide (CuO) into copper sulfate (CuSO4), you would typically need to react it with sulfuric acid (H2SO4). Here's the balanced chemical equation for this reaction:

   CuO + H2SO4 -> CuSO4 + H2O

   In this reaction, copper oxide reacts with sulfuric acid to form copper sulfate and water.

So, to summarize, you can start with copper hydroxide (Cu(OH)2), convert it to copper oxide (CuO) by heating, and then further react the copper oxide with sulfuric acid to produce copper sulfate (CuSO4).
