Answer:
Explanation:
substance x is likely to be Pb(NO3)2------- Lead Nitrate
yellow precipitate is formed during the reaction and it is called lead iodide.
it is an example of double displacement reaction.
it is also an example of a precipitation reaction.
because a precipitate is formed we conclude that it is a chemical reaction
2KI+Pb(NO3)2=2KNO3+PbI2
