Answer:
A) C₅H₁₂O(l) + 7.5 O₂(g) → 5 CO₂(g) + 6 H₂O(l)
B) No reaction
C) SrS(aq) + CuSO₄(aq) → CuS(s)↓ + SrSO₄(aq)
Explanation:
A) liquid pentanol (C₅H₁₂O) and gaseous oxygen.
This is a combustion reaction. assuming the combustion is complete, the products are CO₂ and H₂O.
C₅H₁₂O(l) + 7.5 O₂(g) → 5 CO₂(g) + 6 H₂O(l)
B) aqueous ammonium chloride and aqueous calcium hydroxide.
We could expect a double displacement reaction to take place. But since the products are CaCl₂ and NH₄OH, both of them soluble, no reaction occurs.
C)aqueous strontium sulfide and aqueous copper(II) sulfate.
This is a double displacement reaction. The formed precipitate is CuS.
SrS(aq) + CuSO₄(aq) → CuS(s)↓ + SrSO₄(aq)
