Answer 2

The sequence you've provided, ZnO-ZnCl2-Zn(OH)2-NaZnO2, represents a series of chemical reactions involving zinc and different compounds.

1. ZnO (Zinc Oxide): This is a white powder that is commonly used in various applications, such as in the production of ceramics, pigments, and as a component in sunscreen. It can be obtained by heating zinc metal in the presence of oxygen.

2. ZnCl2 (Zinc Chloride): Zinc chloride is an inorganic compound that is often used as a catalyst in chemical reactions. It can be prepared by dissolving zinc oxide in hydrochloric acid.

3. Zn(OH)2 (Zinc Hydroxide): Zinc hydroxide is a white solid that can be formed by reacting zinc chloride with a strong base such as sodium hydroxide (NaOH). The reaction can be represented as follows:

   ZnCl2 + 2NaOH -> Zn(OH)2 + 2NaCl

4. NaZnO2 (Sodium Zincate): Sodium zincate is an ionic compound formed by the reaction between sodium hydroxide (NaOH) and zinc oxide (ZnO). The balanced equation for this reaction is:

   ZnO + 2NaOH -> Na2ZnO2 + H2O

Overall, the sequence you provided represents a transformation of zinc oxide (ZnO) into sodium zincate (NaZnO2) via the intermediate compounds zinc chloride (ZnCl2) and zinc hydroxide (Zn(OH)2).
