Answer:
Conservation of Mass
-> Mass of Reactants = Mass of Products
-> Na + Cl —> NaCl
-> 26 grams of NaCl, created from 13 grams of Na and 13 grams of Cl
Both
-> Albert Einstein’s Theory of Relativity
-> “Nothing comes from nothing”
Conservation of Energy
-> Cannot be created or destroyed
-> Energy of reactants = Energy of products
-> Endothermic and Exothermic
Those are the answers (I think, I’m not so sure, but pretty confident that they’re correct lol)
