NaF(aq) +--Pb(NO3)2(aq) PDF2(s) + NaNO3(aq) 10.--KBr(aq) +--Pb(NO3)2(aq) PtBr2(s) + KNO3(aq)

Explanation / Answer

Zn + 2HCl ----> ZnCl2 + H2

Mg + Cu(NO3)2 ----> Mg(NO3)2 + Cu (already balanced reaction)

NaOH + HNO3 ----> NaNO3 + H20 (already balanced reaction)

Fe(NO3)3 + 3NaOH ----> Fe(OH)3 + 3NaNO3

2Na +2H20 ---> 2NaOH + H2

AgNO3 + NaCl -----> AgCl + NaNO3 (already balanced reaction)

BaCl2 + H2SO4 -----> BaSO4 + 2HCl

Sr(NO3)2 + H2SO4 ----> SrSO4 + 2HNO3

2NaF + Pb(NO3)2 ----> PbF2 + 2NaNO3

2KBr + Pb(NO3)2 ----> Pb(Br)2 + 2KNO3

2KMnO4 +3H2SO4 ------> 2MnSO4 + K2SO4 + 3H2O + 3/2O2
