Question

K - K2O - KOH - Cu(OH)2 - X?​

Answer 1

Ответ:

Объяснение:

$4K + O_2_(nedostatok) = 2K_2O\\K_2O+H_2O= 2KOH\\2KOH + CuSO_4 = Cu(OH)_2 + K_2SO_4\\Cu(OH)_2 =^t CuO + H_2O$

Answer 2

The given sequence appears to represent a series of chemical compounds involving potassium (K) and copper (Cu). Let's interpret the sequence step by step:

1. K: This represents the chemical symbol for potassium.

2. K2O: This is potassium oxide, where two potassium atoms (2K) combine with one oxygen atom (O).

3. KOH: This is potassium hydroxide, where one potassium atom (K) combines with one hydroxide ion (OH-).

4. Cu(OH)2: This is copper(II) hydroxide, where one copper(II) ion (Cu2+) combines with two hydroxide ions (OH-).

5. X: This indicates an unidentified chemical compound, represented by the letter "X."

Without further information or context, it's challenging to determine the specific compound represented by "X" in the sequence. The sequence could continue with more compounds or reactions, but without additional data, we cannot identify the unknown compound. If you have more context or specific details, please provide them, and I'll do my best to assist you further.
