1) What 2 resources are used up as a candle burns?
2) What has happened to the atoms in these resources?
3) Is it possible to recover these 2 resources after theyve been used?
oxygen and candle wax.
Forms CO2 and water
I think the answer to #3 is no; however, O2 can be recovered with enough time and energy.
1) When a candle burns, two resources are used up: wax and oxygen. The wax is the fuel source for the candle, and the oxygen from the air combines with the wax to produce heat, light, water vapor, and carbon dioxide.
2) During the burning process, the atoms in the wax and oxygen undergo a chemical reaction called combustion. In this reaction, the carbon and hydrogen atoms in the wax combine with the oxygen atoms, breaking the chemical bonds and forming new bonds. This transformation releases energy in the form of heat and light.
3) It is not possible to recover the exact same wax and oxygen molecules after they have been used up in a burning candle. The process of combustion irreversibly transforms the molecules into different compounds. However, it is possible to recover some of the resources indirectly. For example, the carbon dioxide produced during the burning of the candle can be captured and recycled for various industrial purposes. Similarly, the leftover wax can be collected and reused for making new candles, although it would require additional processing.
1) The two resources that are used up as a candle burns are wax and oxygen.
2) During the process of burning, the atoms in these resources undergo chemical reactions. The wax molecules are broken down into smaller molecules, such as carbon dioxide and water vapor, while the oxygen molecules combine with the carbon atoms in the wax to form carbon dioxide.
3) It is not possible to fully recover the resources in their original form once they have been used up and turned into new molecules. However, the carbon dioxide produced during the burning process can be captured and recycled for various purposes, and the remaining wax residue can be reused or recycled in some cases.
