Describe the structure of a complex molecule such as plastic at the molecular level.

Describe the structure of a complex molecule such as plastic at the molecular level. Complex molecules such as plastic contain many atoms that are bonded together that forms a repeating pattern.

Explanation: sorry if its wrong:(

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

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.
