Devante buys a helium birthday balloon for his mom at the grocery store, where the temperature is a comfortable 72of. he takes the balloon outside and places it into his car, where the temperature is 33of and continues his shopping at the clothing store next door. what should he expect the balloon to look like when he returns to the car? why?

The balloon would be smaller and not float as well because of the low temperature. The particles in the balloon when in the car will slow down and get closer together because of the low temperature. That caused it to become more dense and smaller in size then before. When in the store, the particulars in the balloon we’re moving faster and more spread apart

Answer:

a. energy is absorbed in the reaction.

explanation:

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.

The answer is nitrogen-containing bases
