Which of the following reasons explains why electrical cords are plastic coatings with metal wires on the inside? A. Both plastic and metal have high electrical conductivity.

B. Both plastic and metal have low electrical conductivity.

C. Plastic has high electrical conductivity, and metal has low electrical conductivity.

D. Plastic has low electrical conductivity, and metal has high electrical conductivity.

c is the answer because when something is left after something evaporates that shows the chemical change.

the correct answer is:

a. formation of precipitation

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.
