Question

Pb(NO3)2 + 2 KI → PbI2 + 2 KNO3 is an example of which reaction . i)displacement ii)double displacement iii)combination iv)decomposition

Answer 1

Answer:

The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming
