If you don't eat meat, you can still get your iron. Tofu is a good choice. Or go for beans, like kidney, garbanzo, or white. Food from plants has non-heme iron, which means your body doesn't absorb it as well as the heme type found in meat.
Methane is a compound and therefore does not have any atomic number. It is composed of carbon with atomic number 6 and hydrogen with atomic number 1. Methane is a compound and therefore does not have any atomic number. It is composed of carbon with atomic number 6 and hydrogen with atomic number 1.
Berkeley, creator of Physics for Future Preside... A molecule of methane consists of 4 hydrogen atoms and one carbon atom: C H4. Oxygen molecules are O2. To burn (combine) you need two O2 molecules. C H4 + 2 O2 --> CO2 + 2 H2O. The process gives off energy (that means that the outgoing molecules of carbon dioxide (CO2) and water (H2O) have high velocity and heat up the surroundings, perhaps triggering other methane and oxygen molecules to combine (that is, to burn).
