Answer:
- Add more zinc hydroxide.
- Increase the temperature.
Explanation:
Hello,
Based on the given chemical reaction at equilibrium:
Thus, by considering the Le Chatelier's principle, increasing the zinc hydroxide solubility, it means favor the direct reaction, could be attained by:
- Adding more zinc hydroxide as the addition of products favor the formation of products.
- As the reaction is endothermic, the energy is considered as a reactant, therefore, increasing the temperature the direct reaction is favored.
Best regards.
