Final answer:
The elements found in each compound are nitrogen, hydrogen, chlorine in ammonium chloride; potassium, manganese, oxygen in potassium permanganate; carbon, hydrogen, oxygen in isopropyl alcohol; calcium, iodine in calcium iodide.
Step-by-step explanation:
a. The elements found in ammonium chloride (NH₄Cl) are nitrogen (N), hydrogen (H), and chlorine (Cl).
b. The elements found in potassium permanganate (KMnO₄) are potassium (K), manganese (Mn), and oxygen (O).
c. The elements found in isopropyl alcohol (C₃H₈O) are carbon (C), hydrogen (H), and oxygen (O).
d. The elements found in calcium iodide (CaI₂) are calcium (Ca) and iodine (I).
