Which statement best describes how to read a reaction pathway graph for an endothermic reaction? A) Reactants absorb a minimum amount of energy and then release a larger amount of energy as products form.
B) Reactants release a minimum amount of energy and then absorb a larger amount of energy as products form.
C) Reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
D) Reactants release a minimum amount of energy and then absorb a smaller amount of energy as products form.

C) Reactants absorb a minimum amount of energy and then release a smaller  

amount of energy as products form.

Explanation:

The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.

In an endothermic change, heat is absorbed from the surrounding.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
