Which of the following best characterizes the reaction below?

AB + energy → A + B

catabolism
endergonic reaction
exergonic reaction
hydrolysis

Considering the definition of endergonic reaction, the reaction is an endergonic reaction.

Gibbs free energy (or free enthalpy) is a thermodynamic potential, that is, an extensive state function with energy units that gives the condition of equilibrium and spontaneity for a chemical reaction (at constant pressure and temperature).

An endergonic reaction is one that cannot occur spontaneously, and also requires a high energy supply because its products have more energy than the reactants involved in the reaction.

In other words, an endergonic reaction is a reaction in which energy is absorbed. This means that the net free energy change is positive: there is more energy in the system at the end of the reaction than at the beginning.

Because endergonic reactions involve an energy gain, that energy must be supplied from an external source for the reaction to occur.

Finally, the reaction is an endergonic reaction.

Explanation:

Endergonic reactions are reaction that requires a particular amount of energy to initiate the reaction. If there is no energy, the reaction will not occur.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
