`Zn(OH)_(2) undersetto(Delta)[X]`
Select the correct statement (s) for the compound `X`.

Options

A. `X` on heating with cobalt nitrate gives green mass
B. `X` on heating alone, becomess yellow but turns white on cooling
C. Solution of `X` in dilute `HCl` gives bluish white// white precipitate with excees potassium ferrocyanide.
D. None Of These

Explanation

To solve the question regarding the compound \( X \) formed from the thermal decomposition of \( Zn(OH)_2 \), we will analyze the statements provided about \( X \) step by step.

### Step 1: Identify the compound \( X \)
When \( Zn(OH)_2 \) is heated, it decomposes to form \( ZnO \) and water. Therefore, the compound \( X \) is:

\[ X = ZnO \]
