Choosing the Appropriate Property A sample of iodine is easiest to ship as a powder because it is V brittle
making it easy to break into
small pieces.
Helium is less
than the elements that make up the air we breathe, so a balloon filled with
helium will float in air.
Plastic is a compound of nonmetallic elements, so its
properties make it a popular coating
for electric wires to prevent the current from escaping.

explanation:

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.
