Question

Give an example of a double displacement reaction other than the one given in activity 1 . 10

Answer 1

hi...

iodide, potassium nitrate and lead iodide are formed.

Pb(NO3)2 + 2KI –––> 2KNO3 + PbI2

Na2CO3 (aq) + CaCl2 (aq) –––> CaCO3 (s) + 2NaCl (aq)

Here sodium carbonate and calcium chloride exchange ions to form two new compounds

hope it helps u..

Answer 2

$\huge \bf{ \green { answer}}$
sodium carbonate react with calcium chloride to form calcium carbonate and sodium chloride
Na2 O3(aq) + CaCl2 (aq) ----> CaCO3(1) + 2NaCl(aq)
in this reaction sodium carbonate and calcium chloride exchange ions to form New compound has it is double displacement reaction
