10. How were scientists able to discover the Buckyballs in space?

increased stability in the completion of fluorine's outer shell.

fe 55.85 g/mol and h2o 18.02 g/mol.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
