If you stretch back a rubber band and release it, it shoots across the room. what type of energy conversion has occurred?

mechanical to thermal

elastic to chemical

elastic to mechanical

mechanical to elastic

elastic to mechanical

Explanation: According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only be transformed from one form to another.

Elastic energy is the energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed. When the force is removed,  the object gets back to its original shape.The deformation can involve compressing, stretching or twisting of an object.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

answer: a chemical reaction

explanation:

im not wrong

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
