Law of conservation (1 Viewer)

Ah, Hello all, I havent posted in a long time and this question just came to my mind--
If fission results in a slight mass loss (in the form of energy), does this mean the law of conservation doesnt apply?
And, if it does, then when we mix any two chemicals and heat (or anything for that matter) is produced, shouldnt those weights be wrong too?

law of conservation of what? energy or mass? in both cases, the law of conservation is still applied because mass is converted into energy. E=mc² where m is the mass defect, or the missing mass that occurs when fission happens.

The Law of Conservation of Energy still applies in this case because Energy is not created nor destroyed just converted. Binding Energy is part of the Strong Nuclear Force and thus involves the conversion of mass to energy.

However, when mixing chemicals, you are converting potential chemical energy to kinetic (essentially heat) energy. Therefore, the masses will not differ.

So, to TRULY measure mass and energy conservation, you have to know how much energy it expletes as well? then change that to mass and add it all?

If its too much to explain, its ok. I just was sitting here and yeah.. was very curious.
