5. Which combination will produce a precipitate? a) NH4OH(aq) and HCl(aq) b) AgNO3(aq) and CaCl₂(aq) c) NaOH(aq) and HCl(aq) d) NaCl(aq) and H₂SO4(aq) Ans: 6. Based on the solubility rules, will there be a solid formed when solutions of CuSO4(aq) and BaCl2(aq) are mixed? If so, what solid? CuSO4 + BaCl2 → CuCl2 + BaSO4 (A) No solid forms (B) Yes, a solid forms, BaSO4(s) (C) Yes, a solid forms, CuCl₂(s) (D) Two solids form, CuCl₂(s) and BaSO4(s) Ans: 1. HI llowing are strong acids? 2. HNO3 3 & 4 b) 1, 2, 3, & 4 1, 3, & 4 d) 2, 3, & 4 e) 1, 2, & 4 3. HF Ans: 4. HBr 8. Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of H₂SO4 and KOH are mixed. A) H+ (aq) + OH-(aq) → H₂O(l) B) 2 K+ (aq) + SO42-(aq) → K2SO4(s) C) H+ (aq) + OH-(aq) + 2 K+ (aq) + SO42-(aq) → H₂O(1) + K2SO4(s) D) H₂2+(aq) + OH-(aq) → H2(OH)2(1) E) No reaction occurs. in ne r -- as 5.
