Why does every chemical reaction require a certain amount of activation energy? OA.
Energy is released when the reactants begin to react.
OB.
Energy lost to the environment during the reaction must be replaced.
O C.
Forming the activated complex requires energy.
OD.
The products have more potential energy than the activated complex.
E.
The reactants have less potential energy than the products.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

answer: option (b) is the correct answer.

explanation:

intensive property is the physical property which does not depend on the size of system or amount of material present in system.

for example, color, density, melting point, boiling point etc are all intensive properties.

thus, we can conclude that the boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.

effective teamwork and high productivity are good indications of positive

productivity goals.

the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
