Classify the following reaction * Pb(NO3)2 (aq) + 2K1 (ag) → Pbl2 (s) + KNO3 (ag)
O single replacement
double replacement
synthesis
decomposition
combustion

double replacement

Explanation:

The reaction equation is given as:

       Pb(NO₃)₂  +  2KI   →   PbI₂ +   KNO₃

This reaction is a double displacement reaction.

In this form of reaction, there is an actual exchange of partners to form new compounds.

      AB + CD →  AD + CD

One of the following condition serves as driving force for the reaction:

the answer for sodium is 0.186

the answer for rubidium is 0.251

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
