Answer
Explanation:
Step1: Analyze NaOH
Sodium (Na): 1 atom, Oxygen (O): 1 atom, Hydrogen (H): 1 atom. Total atoms = 1 + 1+ 1=3
Step2: Analyze AlCl₃
Aluminum (Al): 1 atom, Chlorine (Cl): 3 atoms. Total atoms = 1 + 3 = 4
Step3: Analyze Mg₃(PO₄)₂
Magnesium (Mg): 3 atoms, Phosphorus (P): 2 atoms, Oxygen (O): 8 atoms. Total atoms = 3+2 + 8=13
Step4: Analyze CuSO₄
Copper (Cu): 1 atom, Sulfur (S): 1 atom, Oxygen (O): 4 atoms. Total atoms = 1+1 + 4=6
Step5: Analyze NH₄Cl
Nitrogen (N): 1 atom, Hydrogen (H): 4 atoms, Chlorine (Cl): 1 atom. Total atoms = 1+4 + 1=6
Step6: Analyze Fe₂O₃
Iron (Fe): 2 atoms, Oxygen (O): 3 atoms. Total atoms = 2+3 = 5
Step7: Analyze H₃PO (assuming it's H₃PO₄)
Hydrogen (H): 3 atoms, Phosphorus (P): 1 atom, Oxygen (O): 4 atoms. Total atoms = 3+1 + 4=8
Step8: Analyze Na₂SO₄
Sodium (Na): 2 atoms, Sulfur (S): 1 atom, Oxygen (O): 4 atoms. Total atoms = 2+1 + 4=7
Answer:
| COMPOUND | ELEMENTS PRESENT IN COMPOUND & HOW MANY OF EACH | TOTAL NUMBER OF ATOMS IN COMPOUND |
|---|---|---|
| NaOH | Na: 1, O: 1, H: 1 | 3 |
| AlCl₃ | Al: 1, Cl: 3 | 4 |
| Mg₃(PO₄)₂ | Mg: 3, P: 2, O: 8 | 13 |
| CuSO₄ | Cu: 1, S: 1, O: 4 | 6 |
| NH₄Cl | N: 1, H: 4, Cl: 1 | 6 |
| Fe₂O₃ | Fe: 2, O: 3 | 5 |
| H₃PO₄ (assuming) | H: 3, P: 1, O: 4 | 8 |
| Na₂SO₄ | Na: 2, S: 1, O: 4 | 7 |
