Simple and Complex Substances

To classify the substances into simple and complex groups, we need to understand the difference between them. Simple substances are made up of only one type of atom or molecule, while complex substances are made up of multiple types of atoms or molecules bonded together.

Let's categorize the given substances into simple and complex groups:

Simple Substances: 1. K2O - Potassium oxide is a simple substance composed of potassium (K) and oxygen (O) atoms. 2. S - Sulfur is a simple substance consisting of sulfur atoms. 3. N2 - Nitrogen gas is a simple substance composed of nitrogen (N) molecules. 4. NaF - Sodium fluoride is a simple substance made up of sodium (Na) and fluorine (F) atoms. 5. CO2 - Carbon dioxide is a simple substance consisting of carbon (C) and oxygen (O) atoms. 6. NaCl - Sodium chloride is a simple substance composed of sodium (Na) and chlorine (Cl) atoms. 7. P - Phosphorus is a simple substance consisting of phosphorus atoms. 8. Li2O - Lithium oxide is a simple substance made up of lithium (Li) and oxygen (O) atoms. 9. P2O3 - Phosphorus trioxide is a simple substance composed of phosphorus (P) and oxygen (O) atoms. 10. Si - Silicon is a simple substance consisting of silicon atoms. 11. NO2 - Nitrogen dioxide is a simple substance made up of nitrogen (N) and oxygen (O) atoms. 12. BeO - Beryllium oxide is a simple substance composed of beryllium (Be) and oxygen (O) atoms. 13. LiF - Lithium fluoride is a simple substance consisting of lithium (Li) and fluorine (F) atoms. 14. C - Carbon is a simple substance consisting of carbon atoms. 15. H2O - Water is a simple substance composed of hydrogen (H) and oxygen (O) atoms. 16. Na2O - Sodium oxide is a simple substance made up of sodium (Na) and oxygen (O) atoms. 17. CH4 - Methane is a simple substance consisting of carbon (C) and hydrogen (H) atoms. 18. K2S - Potassium sulfide is a simple substance composed of potassium (K) and sulfur (S) atoms. 19. P2O5 - Phosphorus pentoxide is a simple substance made up of phosphorus (P) and oxygen (O) atoms. 20. CaCO3 - Calcium carbonate is a simple substance consisting of calcium (Ca), carbon (C), and oxygen (O) atoms. 21. Fe2O3 - Iron(III) oxide is a simple substance composed of iron (Fe) and oxygen (O) atoms. 22. SiO2 - Silicon dioxide is a simple substance made up of silicon (Si) and oxygen (O) atoms. 23. B2O3 - Boron trioxide is a simple substance consisting of boron (B) and oxygen (O) atoms. 24. HNO3 - Nitric acid is a simple substance composed of hydrogen (H), nitrogen (N), and oxygen (O) atoms. 25. MgS - Magnesium sulfide is a simple substance made up of magnesium (Mg) and sulfur (S) atoms. 26. HI - Hydrogen iodide is a simple substance consisting of hydrogen (H) and iodine (I) atoms. 27. SO3 - Sulfur trioxide is a simple substance composed of sulfur (S) and oxygen (O) atoms. 28. Na2O - Sodium oxide is a simple substance made up of sodium (Na) and oxygen (O) atoms. 29. C3H8 - Propane is a simple substance consisting of carbon (C) and hydrogen (H) atoms. 30. MgO - Magnesium oxide is a simple substance composed of magnesium (Mg) and oxygen (O) atoms. 31. O2 - Oxygen gas is a simple substance consisting of oxygen (O) molecules. 32. K2CO3 - Potassium carbonate is a simple substance made up of potassium (K), carbon (C), and oxygen (O) atoms. 33. Li2S - Lithium sulfide is a simple substance composed of lithium (Li) and sulfur (S) atoms. 34. KOH - Potassium hydroxide is a simple substance consisting of potassium (K), oxygen (O), and hydrogen (H) atoms. 35. H3PO4 - Phosphoric acid is a simple substance composed of hydrogen (H), phosphorus (P), and oxygen (O) atoms.

Complex Substances: None of the given substances are complex substances since they are all made up of only one type of atom or molecule.

Please note that the categorization of substances as simple or complex is based on their chemical composition and structure.
