P combination SR decomp DR Bromine water with aqueous potassium chloride 6. 7. Bromine water with aqueous potassium iodide SR DR combination decomp 8. Red phosphorus ignited in a flame SR DR decomp combination 9. Gas product from reaction 8 mixed with water SR DR decomp combination 10. Mossy zinc with hydrochloric acid SR. DR decomp combination

Answer 1

Answer 6):- Br_{2 (aq)} +  KCl (aq)  $\rightarrow$ No Reaction. This is because Br is less reactive to replace Cl atom from its salt.

Answer 7):- Br_{2 (aq)} + 2 KI (aq)  $\rightarrow$ 2 KBr (aq) + I_{2 (aq)} . Single displacement reaction (SR)

Answer 8):- 4 P + 5 O₂ $\rightarrow$ P₄O₁₀ + Heat . Combination reaction.

Answer 9):- P₄O₁₀ + 6 H₂O  $\rightarrow$ 4 H₃PO₄ . Combination reaction.

Answer 10) Zn (s) + 2 HCl (aq) $\rightarrow$ ZnCl_{2 (aq)} + H_{2 (g).} Single displacement reaction (SR).
