The formations of these compounds from elements are as follows.
2 Na + S --> Na2S
2K + I2 --> 2KI
These two reagents do not react with each other.
The balanced equation is 2 KI + Pb(NO3)2 -> 2 KNO3 + PbI2.
Me too i don't know
There is no reaction, because all product ( if reaction goes) would be soluble. so : H+ + Cl- + K+ + I- = H+ + Cl- + K+ + I- and than all of them dare present as a ions only.
Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
Formula: KI
