Question

K2SiO3 + Pb = K2SiO3 + Ca = K2SiO3 + Na2S =

Answer 1

K2SiO3 + Pb = Pb(SiO3) 2+2K
K2SiO3 +Ca = CaSiO3 +2K
K2SiO3+Na2S = Na2SiO3 +K2S

Answer 2

The chemical equations you provided involve reactions with potassium metasilicate (K2SiO3) and various other substances. However, the equations are not balanced, and it's unclear what the desired products or conditions are. I'll attempt to balance these equations for you, but please provide more context if you have specific reaction conditions or products in mind.

1. K2SiO3 + Pb = ?

   To balance this equation, we need more information about the reaction. Assuming it's a simple displacement reaction, it could be balanced as:

   2K2SiO3 + 3Pb → 2K2SiO3 + 3PbO

2. K2SiO3 + Ca = ?

   Again, without additional information, I'll assume a simple displacement reaction:

   K2SiO3 + Ca → CaSiO3 + 2K

3. K2SiO3 + Na2S = ?

   Once more, assuming a displacement reaction:

   K2SiO3 + Na2S → Na2SiO3 + 2K2S

Please provide more context or specific reaction conditions if you have a different reaction or desired products in mind.
