In the air, several substances are considered compounds. The most notable examples include carbon dioxide (CO2), which is a combination of carbon and oxygen, and water vapor (H2O), formed from hydrogen and oxygen. Other compounds present in smaller amounts include ozone (O3) and sulfur dioxide (SO2). These compounds play significant roles in various atmospheric processes and environmental impacts.
No: Compounds are simple mixtures of substances
efflorescent substances are substances which looses moisture partly or completely to the atmosphere and changes in to amorphous powder. deliquecent substances are substances which absorb moisture from the atmosphere and turn into a saturated solution.
The air, soil, and most foods and beverages are examples of mixtures. Mixtures consist of two or more different substances that are physically combined but not chemically bonded. They can vary in composition and can include elements and compounds within them. In contrast, pure substances consist of only one type of particle.
Gold, Silver, Oxygen, and Hydrogen are not compounds because they are all elements.Sources- Science book. ^_^P.S- This better have helped!
