Pb(NO3)2 + 2KCl ---> PbCl2 + 2KNO3
It is impossible to balance that equation.
its already balanced
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
Oxygen is present in both zinc nitrate and potassium chlorate. Potassium chlorate = KClO3 and zinc nitrate = ZnNO3 .
2KNO3 (s) ==heat==> 2KNO2(s) + O2(g) potassium nitrate decomposes to potassium nitrite and oxygen. NB Note the spelling for the product.
The balanced equation is 2 KI + Pb(NO3)2 -> 2 KNO3 + PbI2.
Kn2 heat equal kn2+o2
Your balanced chemical equation for this double replacement reaction would be: Cu(NO3)2 + 2KOH ----> Cu(OH)2 + 2KNO3 Therefore, you would end up with copper II hydroxide and potassium nitrate.
2KOH + Ba(NO3)2 -----> 2KNO3 + Ba(OH)2
No reaction
Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
The most common oxidisers used in fireworks are: Potassium nitrate, KNO3 Barium nitrate, Ba(NO3)2 Strontium nitrate, Sr(NO3)2 Sodium nitrate, NaNO3 Potassium chlorate, KClO3 Potassium perchlorate, KClO4 Ammonium perchlorate, NH4ClO4
