Answer 1

1)Na2O+H2O=2NaOH

NaOH+HNO3=NaNO3+H2O

 

 2)K2O+H2O=2KOH

2KOH+H2CO3=K2CO3+2H2O

3)2CU+O2=2CuO

CuO+2HCL=Cucl2+h2o

CuCl2+2NaOH=CU(OH)2+2NACL

CU(OH)2=CUO+H2O

 

 

 

 

 

 

 

 

 

 

 

 

Answer 2

It looks like you've provided a chemical reaction sequence. Let's break it down step by step.

Chemical Reaction Sequence:

The given sequence of chemical reactions involves the transformation of various elements and compounds. Let's break it down step by step:

1. Sodium (Na) - Sodium reacts with water to form sodium hydroxide (NaOH). - The reaction can be represented as: ``` 2Na + 2H2O -> 2NaOH + H2 ```

2. Sodium Hydroxide (NaOH) - Sodium hydroxide reacts with nitric acid to form sodium nitrate (NaNO3). - The reaction can be represented as: ``` NaOH + HNO3 -> NaNO3 + H2O ```

3. Potassium (K) - Potassium reacts with water to form potassium hydroxide (KOH). - The reaction can be represented as: ``` 2K + 2H2O -> 2KOH + H2 ```

4. Potassium Hydroxide (KOH) - Potassium hydroxide reacts with copper(II) sulfate to form potassium sulfate and copper(II) hydroxide. - The reaction can be represented as: ``` 2KOH + CuSO4 -> K2SO4 + Cu(OH)2 ```
