o reaction\ is a possible outcome

1. ____pb(no₃)₂ + ____ki →
2. ____cuso₄ + ____naoh →
3. ____li₂so₄ + ____nh₄no₃ →
4. ____fecl₃ + ____na₂co₃ →
5. ____na₂s + ____baso₄ →

Explanation:

Step1: Balance & predict reaction 1

Double displacement: $Pb(NO_3)_2 + 2KI
ightarrow PbI_2 \downarrow + 2KNO_3$

Step2: Balance & predict reaction 2

Double displacement: $CuSO_4 + 2NaOH
ightarrow Cu(OH)_2 \downarrow + Na_2SO_4$

Step3: Balance & predict reaction 3

No precipitate (all soluble): $Li_2SO_4 + 2NH_4NO_3
ightarrow 2LiNO_3 + (NH_4)_2SO_4$ (No Reaction)

Step4: Balance & predict reaction 4

Double displacement: $2FeCl_3 + 3Na_2CO_3
ightarrow Fe_2(CO_3)_3 \downarrow + 6NaCl$

Step5: Balance & predict reaction 5

Double displacement: $Na_2S + BaSO_4
ightarrow BaS \downarrow + Na_2SO_4$

Answer:

1. $Pb(NO_3)_2 + 2KI

ightarrow PbI_2 \downarrow + 2KNO_3$

1. $CuSO_4 + 2NaOH

ightarrow Cu(OH)_2 \downarrow + Na_2SO_4$

1. $Li_2SO_4 + 2NH_4NO_3

ightarrow 2LiNO_3 + (NH_4)_2SO_4$ (No precipitate formed)

1. $2FeCl_3 + 3Na_2CO_3

ightarrow Fe_2(CO_3)_3 \downarrow + 6NaCl$

1. $Na_2S + BaSO_4

ightarrow BaS \downarrow + Na_2SO_4$
