Answer 1

1.
ZnSO4+H2
2.
ZnO+2HCL=ZnCl2+H2O
3.
MgO + SiO2 → MgSiO3

Answer 2

It looks like you're trying to describe a series of chemical reactions. Let me break down each step for you:

1. Zn + H2SO4: Zinc (Zn) reacts with sulfuric acid (H2SO4) to form zinc sulfate (ZnSO4) and hydrogen gas (H2).

$\text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2$

2. ZnO + HCl: Zinc oxide (ZnO) reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and water (H2O).

$\text{ZnO} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2\text{O}$

3. NGO + SiO2: I'm not sure what "NGO" refers to in this context. If it's a chemical compound, please provide its full name, and I can help you balance the equation accordingly.

If you have any other questions or if you can provide more information about "NGO," please let me know!
