Al2O3 + H20

Answer 2

It looks like you've provided a series of chemical reactions involving various compounds. However, the reactions are not complete as they lack the information about the states of matter and the balancing coefficients. I'll help you complete and balance these reactions:

1. ZnO + SiO2 → ZnSiO3

2. Zn(OH)2 + Ca(OH)2 → Zn(OH)4 + Ca(OH)2

3. Al(OH)3 + 3HNO3 → Al(NO3)3 + 3H2O

4. Al(OH)3 + 3LiOH → Al(OH)6Li3

5. Al(OH)2- + H2O → Al(OH)3

Please note that in some cases, I've made assumptions about the states of matter (e.g., assuming ZnO and SiO2 react to form ZnSiO3). Additionally, I've balanced the equations based on the information provided, but it's possible that there are other forms or states of these compounds that could lead to different reactions. If you need more specific information or have other questions, feel free to ask!
