Answer 1

Answer:

Pb(NO 3 ) 2 (aq)+2KI(aq)→PbI(s)+2KNO 3 (aq)

Above reaction is a precipitation and a double displacement reaction in which solid precipitates of lead iodide (PbI) are formed .Therefore x represents solid (s) form of lead iodide and y represents aqueous (aq) form of potassium nitrate.
