Question

CuO =>CuSO4 => Cu(OH)2 => CuO

Answer 1

CuO =>CuSO4 => Cu(OH)2 => CuO
1)2Cu+O²⇒2CuO
2)CuO+SO3⇒CuSO4
3)CuO+H2O⇒Cu(OH)2
4)Cu(OH)2⇒CuO+H2O

Answer 2

The series of reactions you've provided involves the conversion of copper(II) oxide (CuO) through several steps. Let's go through each reaction step by step:

1. CuO => CuSO4: This reaction involves the reaction of copper(II) oxide with sulfuric acid (H2SO4) to form copper(II) sulfate (CuSO4) and water (H2O). The balanced equation for this reaction is:

CuO + H2SO4 -> CuSO4 + H2O

2. CuSO4 => Cu(OH)2: In this step, copper(II) sulfate (CuSO4) reacts with a base, typically sodium hydroxide (NaOH), to form copper(II) hydroxide (Cu(OH)2) and sodium sulfate (Na2SO4). The balanced equation for this reaction is:

CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4

3. Cu(OH)2 => CuO: This reaction involves the dehydration of copper(II) hydroxide (Cu(OH)2) to form copper(II) oxide (CuO). When heated, Cu(OH)2 loses water molecules and converts into CuO. The balanced equation for this reaction is:

Cu(OH)2 -> CuO + H2O

Therefore, the overall reaction sequence is:

CuO + H2SO4 -> CuSO4 + H2O CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4 Cu(OH)2 -> CuO + H2O

Please note that these reactions are presented in a general sense and may require specific reaction conditions (such as temperature, concentration, etc.) for optimal yield.
