(II) name the substance which the yellow solid consist of. (iii) which characteristics of the chemical reaction is illustrated by this example. (iiii) write a balance equation for the reaction which takes place , mention the physical state of all the reactants and products. ​

Answer 1

Answer:

X- Lead Nitrate (II) Lead iodide (iii) formation of precipitation is being shown here (iiii) Pb(NO₃)₂+2KI => PbI₂=2KNO₃

Explanation:

Answer 2

(a) Lead nitrate. 

(b) Lead iodide. 

(c) Formation of a precipitate. 

(d) Pb(NO3)2 + 2KI —–> PbI2 + 2KNO3.
