Answer 2

Chemical Reaction: CuO -> Cu -> CuCl2 -> Cu(OH)2 -> CuSO4

The given chemical reaction sequence involves the transformation of copper oxide (CuO) into copper sulfate (CuSO4) through several intermediate steps. Let's break down each step:

1. CuO -> Cu: The first step is the reduction of copper oxide (CuO) to elemental copper (Cu). This reduction reaction can be achieved by heating CuO in the presence of a reducing agent such as hydrogen gas (H2) or carbon monoxide (CO). The reaction can be represented as follows: ``` CuO + H2 → Cu + H2O ``` or ``` CuO + CO → Cu + CO2 ``` 2. Cu -> CuCl2: The next step involves the reaction of elemental copper (Cu) with chlorine gas (Cl2) to form copper chloride (CuCl2). This reaction is an example of a synthesis reaction. The balanced equation for this reaction is: ``` Cu + Cl2 → CuCl2 ``` 3. CuCl2 -> Cu(OH)2: Copper chloride (CuCl2) can react with a base, such as sodium hydroxide (NaOH), to form copper hydroxide (Cu(OH)2). The balanced equation for this reaction is: ``` CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl ``` 4. Cu(OH)2 -> CuSO4: Copper hydroxide (Cu(OH)2) can further react with sulfuric acid (H2SO4) to produce copper sulfate (CuSO4). The balanced equation for this reaction is: ``` Cu(OH)2 + H2SO4 → CuSO4 + 2H2O ``` [[3]](https://inmt.urfu.ru/fileadmin/user_upload/site_15053/zaochno/Departament_metallurgii_osn_stranica/KHimija/KHimija._Uchebnoe_posobie..pdf)

Therefore, the complete chemical reaction sequence is as follows: CuO -> Cu -> CuCl2 -> Cu(OH)2 -> CuSO4.

Please note that the specific reaction conditions, such as temperature, pressure, and concentration, may affect the reaction rates and product yields.
