“Ummm. No. It is not. Even if you use all caps.... it still is not.”
YES it is. E=MC^2 is a universal equation.
No it is not .
E=mc2 is the equation relating energy (e) to its mass equivalent (m). A fire (burning) uses no mass. Its energy release is in the electron bonds.
Whereas in fission, a nuclear, not a chemical, energy release is in the form of mass (a small amount) being converted to energy (a Large amount).
No. Burning has naught to do with E=mc2.
Even if there were some nuclear component of the chemical reaction known as “burning”, the vast majority of energy released is from the rearrangement of molecular bonds in hydrocarbons to form CO, CO2 and HOH.
