Answer 1

1a. Consider the following reaction:

2HBr(aq)+Sr(OH)₂(aq) → 2H₂O(l)+SrBr₂(aq)

2H⁺(aq) + 2Br^-1(aq) + Sr²⁺(aq) + 2OH^-(aq) -----> 2H₂O(l) + Sr²⁺(aq) + 2Br^-1(aq)

1b. liquid propanol (C3H8O) and gaseous oxygen  2C₃H₈O (l) + 9O₂ (g) ----> 6CO₂ (g) + 8 H₂O(l)

1c. aqueous strontium sulfide and aqueous copper(II) sulfate

SrS (aq) + CuSO₄ (aq) ---> SrSO₄ (s) + CuS (s)
