Ron wants to install an energy efficient and long lasting device for lighting in his new home. which device should he use?

Light Emitting Diode (LED) lighting device.

Explanation:

Light Emitting Diode (LED) is an electrical component that produces light when a current flows through its terminals. It has a long life span and conserves energy coupled with brilliant lightning effects. Also, it is light in weight and generate no heat compared to other lighting devices. It is majorly recomended because of its diverse properties and efficient functions.

This componet can be incorporated to produce an energy efficient and long lasting lighting device. So, Ron should use a Light Emitting Diode (LED) lighting device.

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.
