Как из K2O сделать K3Po4 как из KOH сделать Cu(OH)2 Как из Cu(Oh)2 сделать CuO как из CuO сделать Cu

Answer 1

Возможно Cu +++++++++++++++++++

Answer 2

1) 3P2O5+K2O=2K3PO4
2) CuCl2+2KOH=Cu(OH)2+2KCl2
3) Cu(OH)2=CuO+H2O
4) 2CuO=2Cu+O2 или CuO+H2=Cu+H2O

Answer 3

Converting K2O to K3PO4

To convert K2O to K3PO4, you would need to react K2O with phosphoric acid (H3PO4). The balanced chemical equation for this reaction is:

2 K2O + 3 H3PO4 → 2 K3PO4 + 3 H2O

In this reaction, two molecules of K2O react with three molecules of H3PO4 to produce two molecules of K3PO4 and three molecules of water (H2O).

Converting KOH to Cu(OH)2

To convert KOH to Cu(OH)2, you would need to react KOH with a copper(II) salt, such as copper(II) sulfate (CuSO4). The balanced chemical equation for this reaction is:

2 KOH + CuSO4 → Cu(OH)2 + K2SO4

In this reaction, two molecules of KOH react with one molecule of CuSO4 to produce one molecule of Cu(OH)2 and one molecule of K2SO4.

Converting Cu(OH)2 to CuO

To convert Cu(OH)2 to CuO, you would need to heat Cu(OH)2. The thermal decomposition of Cu(OH)2 yields CuO and water. The balanced chemical equation for this reaction is:

Cu(OH)2 → CuO + H2O

In this reaction, Cu(OH)2 decomposes to form CuO and water (H2O) when heated.

Converting CuO to Cu

To convert CuO to Cu, you would need to reduce CuO. One common method to reduce CuO is to heat it with hydrogen gas (H2) or carbon monoxide (CO). The balanced chemical equation for this reaction using hydrogen gas is:

CuO + H2 → Cu + H2O

In this reaction, CuO reacts with hydrogen gas to produce Cu and water (H2O).
