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:

<em>A) liquid pentanol (C₅H₁₂O) and gaseous oxygen.</em>

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)

<em>B) aqueous ammonium chloride and aqueous calcium hydroxide.</em>

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.

<em>C)aqueous strontium sulfide and aqueous copper(II) sulfate.</em>

This is a double displacement reaction. The formed precipitate is CuS.

SrS(aq) + CuSO₄(aq) → CuS(s)↓ + SrSO₄(aq)
