Question

Na2[Cu(OH)4] ---> CuSO4

Answer 1

The chemical equation you provided is the reaction between sodium hydroxide (NaOH) and copper(II) sulfate (CuSO4). The balanced equation for this reaction is:

2NaOH + CuSO4 → Na2SO4 + Cu(OH)2

In this reaction, sodium hydroxide reacts with copper(II) sulfate to form sodium sulfate and copper(II) hydroxide. However, copper(II) hydroxide is not stable and tends to decompose into copper(II) oxide and water. The balanced equation for the decomposition of copper(II) hydroxide is:

Cu(OH)2 → CuO + H2O

So, the overall reaction can be written as:

2NaOH + CuSO4 → Na2SO4 + CuO + H2O

Please note that the reaction you provided, Na2[Cu(OH)4] → CuSO4, is not balanced and does not represent a valid chemical reaction.
