Question

Sо4 - ZnSO, - Zn(OH)2 - Zno - So,​

Answer 1

Ответ:

1)2Zn + O2 = 2ZnO  - знаменитая реакция сгорания цинка на воздухе)

2)ZnO + H2SO4 =ZnSO4 + H2O

3)ZnSO4 +2 NaOH = Zn(OH)2 + Na2SO4  

4)Zn(OH)2=ZnO+H2O- разложение гидроксида цинка, при температуре)

Answer 2

It appears that you've provided a sequence of chemical compounds or reactions involving sulfur, zinc, and oxygen, but the notation is a bit unclear. I'll try to interpret what you've written:

1. SO4 - This typically represents the sulfate ion (SO4^2-), which is a polyatomic ion composed of one sulfur atom (S) and four oxygen atoms (O).

2. ZnSO - It seems like you might be referring to zinc sulfate (ZnSO4), which is a chemical compound composed of one zinc (Zn) atom, one sulfur atom (S), and four oxygen atoms (O).

3. Zn(OH)2 - This is zinc hydroxide (Zn(OH)2), a chemical compound consisting of one zinc atom (Zn) and two hydroxide ions (OH^-).

4. ZnO - This is zinc oxide (ZnO), a chemical compound composed of one zinc atom (Zn) and one oxygen atom (O).

5. So - This doesn't appear to be a recognized chemical species. It's possible there may be a typo or a missing element.

6. If you intended to write "SO," it could represent sulfur dioxide (SO2), a gas composed of one sulfur atom (S) and two oxygen atoms (O).

Please clarify your question or provide more context so that I can give you a more accurate response. If you have a specific chemical reaction or question in mind, please describe it in more detail.
