Question

Получить из K2PbO2->Pb(OH)2

Answer 1

$K_{2} PbO_{2} +2HCl=Pb(OH)_{2} +2KCl$

Answer 2

K2PbO2 + 2HCl(недостаток) ----> Pb(OH)2 + 2KCl 

Answer 3

Balancing the Chemical Equation

To obtain Pb(OH)2 from K2PbO2, we need to balance the chemical equation for the reaction. The balanced chemical equation for the reaction can be represented as follows:

2K2PbO2 + 2H2O → 2Pb(OH)2 + 4KOH

Explanation of the Reaction

In this reaction, K2PbO2 reacts with water to produce Pb(OH)2 and potassium hydroxide (KOH). The balanced equation ensures that the same number of each type of atom is present on both sides of the equation, satisfying the law of conservation of mass.

Conclusion

By balancing the chemical equation, we can see that to obtain Pb(OH)2 from K2PbO2, we need to react K2PbO2 with water. This will result in the formation of Pb(OH)2 and KOH.
