Answer 1

Вот решение. По идее все правильно.  :3
Не за что)

Answer 2

2Na+2H2O=2NaOH+H2

2NaOH+H2SO4=Na2SO4+2H2O

Na2SO4+2HCl=H2SO4+2NaCl

Answer 3

Chemical Transformations

Chemical transformations involve the conversion of one or more substances into different substances through chemical reactions. Here are a few examples of chemical transformations:

1. Aluminum Carbide to Methane and Aluminum Hydroxide: The reaction between aluminum carbide (Al4C3) and water (H2O) produces methane (CH4) and aluminum hydroxide (Al(OH)3). ``` Al4C3 + 12H2O → 4Al(OH)3 + 3CH4 ```

2. Methane to Chloromethane: Methane (CH4) can react with chlorine (Cl2) to form chloromethane (CH3Cl) and hydrogen chloride (HCl). ``` CH4 + Cl2 → CH3Cl + HCl ```

3. Chloromethane to Ethane: Chloromethane (CH3Cl) can react with sodium (Na) to produce ethane (C2H6) and sodium chloride (NaCl). ``` 2CH3Cl + 2Na → C2H6 + 2NaCl ```

4. Ethane Combustion: Ethane (C2H6) can undergo combustion with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). ``` 2C2H6 + 7O2 → 4CO2 + 6H2O ```

5. Copper Oxide Reactions: Copper oxide (CuO) can undergo various transformations. For example: - Copper oxide reacts with sulfuric acid (H2SO4) to form copper sulfate (CuSO4) and water (H2O). ``` CuO + H2SO4 → CuSO4 + H2O ``` - Copper sulfate reacts with potassium hydroxide (KOH) to produce copper hydroxide (Cu(OH)2) and potassium sulfate (K2SO4). ``` CuSO4 + 2KOH → Cu(OH)2 + K2SO4 ``` - Copper hydroxide can decompose into copper oxide and water. ``` Cu(OH)2 → CuO + H2O ``` - Copper oxide reacts with hydrochloric acid (HCl) to form copper chloride (CuCl2) and water (H2O). ``` CuO + 2HCl → CuCl2 + H2O ```

Please note that these are just a few examples of chemical transformations, and there are many more reactions and combinations possible.
