1] CaF₂ + Li₂So₄ → CaSo₄ + 2 LiF

2] 2 HBr + Mg(OH)₂ → MgBr₂ + 2 H₂O

3] AgNO₃ + Li → LiNO₃ + Ag

4] Equation Fe₂O+PbF₂→FeF₂+PbO is an impossible reaction

Did you mean FeO + PbF₂ → FeF₂ + PbO ?

balanced equation is: FeO + PbF₂ → FeF₂ + PbO

5] 2 Mn + 6 HI → 3 H₂ + 2 MnI₃

6] P₄ + 3 O₂ → 2 P₂O₃ 

7] 2 AgNO₃ + Cu → Cu(NO₃)₂ + 2 Ag

8] 2 Na₃P + 3 CaF₂ → 6 NaF + Ca₃P₂

9] Equation CH₄+O₂ → NaF+Ca₃P₂ is an impossible reaction.
Please correct your reaction to:
CH₄ + O₂ → CO₂ + H₂O

balanced equation is: CH₄ + 2 O₂ → CO₂ + 2 H₂O

10] Al₂(SO₄)₃ + 6 NaOH → 2 Al(OH)₃ + 3 Na₂SO₄
