What happens when an electron absorbs energy? the electron moves from a lower energy orbital to a higher energy orbital. the electron falls into the nucleus. the electron moves from a higher energy orbital to a lower energy orbital. the electron loses its charge.

A) The electron moves from a lower energy orbital to a higher energy orbital.

I hope this helped ya :) 

The answer is A. The electron moves from a lower energy orbital to a higher energy orbital. Because if it's absorbing energy it will have more energy than before.

D. most models represent a real world object in a simpler way

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
