Hi everyone!

Do you know why fatty acids burn in the presence of carbon? I found some explanations on the internet but they didn't help me. Can you explain me (in simple terms) why fatty acids burn in the presence of carbon ?

No idea what you mean. Not only they contain carbon by themselves, all they need to burn is oxygen.

1. Why do fatty acids burn in the presence of carbon?

Fatty acids are made up of long chains of carbon and hydrogen atoms. When they are exposed to heat and oxygen, a chemical reaction called combustion occurs, breaking down the bonds between these atoms and releasing energy in the form of heat and light. This process is what we commonly refer to as burning.

2. Is carbon the only element needed for fatty acids to burn?

No, oxygen is also required for fatty acids to burn. Without oxygen, the combustion reaction cannot occur and the fatty acids will not burn.

3. Why do fatty acids produce more energy when they burn compared to other substances?

Fatty acids contain a large number of carbon-hydrogen bonds, which are high in energy. When these bonds are broken during combustion, a significant amount of energy is released. This is why fatty acids are often used as a source of fuel or energy.

4. Are all fatty acids flammable?

Yes, all fatty acids are flammable in the presence of oxygen and heat. However, the ease at which they burn may vary depending on the length and structure of the fatty acid chain.

5. Can fatty acids burn without the presence of oxygen?

No, fatty acids require oxygen in order to burn. This is because oxygen is needed to break down the carbon-hydrogen bonds and release energy. In the absence of oxygen, fatty acids will not undergo combustion and will not burn.
