Question

Здійснити перетворення:калій>калію оксид>калію гідроксид>калію бромід>калій>калію ортофосфат

Answer 1

K->K2O->KOH->KBr->K->K3PO4
4K+O2=2K2O
K2O+H2O=2KOH
KOH+HBr=KBr+H2O
2KBr=2K+Br2
6K+2H3PO4=2K3PO4+3H2

Answer 2

Transformation of Potassium (K):

The transformation of potassium (K) can be described as follows:

1. Potassium (K) to Potassium Oxide (K2O): - Potassium reacts with oxygen to form potassium oxide. - The balanced chemical equation for this reaction is: 2K + O2 → 2K2O. - Potassium oxide is a compound composed of two potassium atoms and one oxygen atom.

2. Potassium Oxide (K2O) to Potassium Hydroxide (KOH): - Potassium oxide reacts with water to form potassium hydroxide. - The balanced chemical equation for this reaction is: K2O + H2O → 2KOH. - Potassium hydroxide is a strong base commonly used in various industries.

3. Potassium Hydroxide (KOH) to Potassium Bromide (KBr): - Potassium hydroxide reacts with hydrobromic acid (HBr) to form potassium bromide and water. - The balanced chemical equation for this reaction is: KOH + HBr → KBr + H2O. - Potassium bromide is a salt that is often used in medicine and photography.

4. Potassium Bromide (KBr) to Potassium (K): - Potassium bromide can be reduced to potassium by reacting it with a more reactive metal, such as magnesium. - The balanced chemical equation for this reaction is: 2KBr + Mg → 2K + MgBr2.

5. Potassium (K) to Potassium Orthophosphate (K3PO4): - Potassium reacts with orthophosphoric acid (H3PO4) to form potassium orthophosphate and hydrogen gas. - The balanced chemical equation for this reaction is: 3K + H3PO4 → K3PO4 + 3H2. - Potassium orthophosphate is a compound commonly used as a fertilizer.

Please note that the above transformations are based on chemical reactions and may require specific conditions, such as temperature and pressure, to occur.
