A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by the reaction ATP ( aq ) + H 2 O ( l ) ⟶ ADP ( aq ) + HPO 2 − 4 ( aq ) for which Δ G ∘ rxn = − 30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of Δ G rxn in a biological cell in which [ ATP ] = 5.0 mM, [ ADP ] = 0.20 mM, and [ HPO 2 − 4 ] = 5.0 mM.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
