The breakdown of glycogen (an energy-storage compound) is an example of a(n) reaction.

The answer is exergonic.

The breakdown of glycogen (an energy-storage compound) is an example of an exergonic reaction.

An exergonic reaction is one in which flow of heat occurs from system to surrounding.

In breakdown of glycogen , energy is released from system to surrounding , so it is an example of an exergonic reaction.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
