Incorrect Statement Identification
The statement that is incorrect is: "glucose is not a pure substance."
Explanation of Glucose
- Glucose is a simple sugar and is indeed a pure substance.
- It has a specific chemical formula (C6H12O6) and consistent properties, making it a pure compound.
Elements and Compounds
- Elements: Sodium, copper, silicon, and hydrogen are all classified as elements.
- Compounds: Water (H2O), ammonia (NH3), sugar (C6H12O6), and carbon dioxide (CO2) are all pure compounds, composed of two or more elements chemically bonded together.
Physical States of Substances
- Gases: Hydrogen (H2) and oxygen (O2) are gases at room temperature.
- Liquid: Water, the compound formed from hydrogen and oxygen, is a liquid at room temperature.
Conclusion
- The only incorrect assertion in the statements provided pertains to glucose. It should be recognized as a pure substance, while all other statements regarding elements and compounds are accurate. Understanding the distinction between pure substances and mixtures is crucial in chemistry, especially in the context of NEET examinations.
