I know this sounds like a silly question but when a candle bought at Yankee Candle burns away, and the jar is empty, is there a waxy coating on the walls of my room? Would one eventually over the years, be able to notice the waxy coating in the room? Are we breathing in wax while the candles burning? I have a lot of questions just like a five-year-old LOL. Someone please help.
In: Chemistry
The same thing which happens when you burn gasoline, wood, fat, carbohydrates or other hydrocarbons: It combines with oxygen from the air into CO₂ and water. The reaction releases energy (heat).
It’s the same thing when you lose body weight: You use oxygen from the air to burn fat which is exhaled as CO₂ from your lungs.
Fun fact: Plants get most of their solid mass from the air. They are mostly carbon which they get from CO₂. Doing so requires energy which they get from the sun via photosynthesis.
