I think the correct answer is a. water and carbon dioxide are coming out according to the arrows, so it isn't being stored so the answer isn't C. oxygen is going in according to the arrows, not out so it isn't b. it doesn't say anything about simple organisms so using the process of elimination, it looks like A is correct.
The answer is N2 + 3H2 yields 2NH3. The oxidation-reduction reaction means that there is electrons transfer during the reaction which means that the valence changed.
Pros it will sustain our daily needs and will never run out
As velocity increases, so does kinetic energy
Answer and Explanation:
The water is a polar solvent which dissolves into the LiBr molecules and converts into 
and 
ions far from the solid also into the solution, when they are hydrated.
Now, the complete words are as given below:-
The 
and 
ions at the surface of the solid are pulled into the solution by the polar water molecules, where the hydration process surrounds separate ions with water molecules.
