What type of reaction is pb(no3)2(aq) + 2kcl(aq) ® pbcl2(s) + 2kno3(aq)?
Sladkaya [172]

The given reaction is,

Pb(NO_{3})_{2}(aq) +2 KCl(aq) --->PbCl_{2}(s) + 2 KNO_{3}(aq)

In this reaction, the positive and negative ions of both the reactants rearrange resulting in the formation of new compounds. Such a reaction is referred to as the double replacement or the double displacement reaction. These type of reactions usually take place in aqueous medium and one of the products is a precipitate.

Double displacement reactions are of three types, precipitation reaction, neutralization reaction and reaction involving the formation of a gas. The given reaction is a precipitation reaction as one of the products is a solid.

choli [55]
<span> It is a little hard to explain step-by-step what to do so I hope you can follow what to do by looking at how I arranged the equations.

2 H2O(g) --------------------------> 2 H2O(l) -88
2 H2 + O2 ----------------------------> 2 H2O(g) -484
C + O2 ----------------------------> CO2 -393.5
CH4 -------------------------------> C + 2 H2 + 74.8
________________________________________...
CH4 + 2 O2 ---------------------> CO2 + 2 H2O -890.6 kJ

Once you cancel out the substances that appear BOTH on the left AND the right of the arrows you are left with your net equation. </span>
