HMX Biochemistry Exam Questions With Verified Solutions Synthesis - answerATP synthase couple the exergonic movement of H+ ions down a concentration gradient to the endergonic _______ of ATP from ADP and Pi outer and inner - answerMitochondria has 2 membranes: ________ unfavorable - answerReaction with a positive change in free energy are thermodynamically favorable - answerreaction with a negative free energy(G) are thermodynamically Energy - answerability to do work coordinate diagram ...

What happens in a spontaneous reaction? - correct answer the total entropy of the universe must increase. Change in Free Energy - correct answer -tells position and direction of a reaction -easier to calculate than entropy 1st law of thermodynamics - correct answer the energy of the universe is constant. (any energy lost by system is gained by surroundings and vice versa) 2nd law of thermodynamics - correct answer the entropy of the universe increases in any spontaneous process 3rd ...

CEM 142 Exam 1 Latest Version Already Graded A Open system mass/matter as well as energy can flow in and out of the system closed system mass/matter can not flow into the system but energy can flow in and out of the system isolated system nothing can enter or leave the system what is the difference between state and path function State function depend only on the initial and final states but not the path taken while a path function requires multiple steps and proofs to get to t...

Chem Exam: Types of Calculation Questions & Answers 100% Verified Calorimetry Calculations: 1. 2.50 kJ of energy changes the temperature of a sample of lead by 8.52 degrees C. What is the mass of the sample? - ANS-Q = mcΔT m=Qc/Δt m = 2500/0.13(8.52) = 2.3×103 g 2. 950.3 J of energy is removed from 28.5 g of water at 80.3 degrees C. What is the final temperature? - ANS-Q = mcΔT −950.3 = 28.5(4.18)(T2 − 80.3) T2 = −950.3/(28.5)(4.18) + 80.3 = 72.3O C 3. A 30.56 g sample...

What is the most important thing change in Gibbs free energy tells us? What does a negative value mean and what does a positive value mean? - how spontaneous a reaction is negative delta G = spontaneous, energy is released, exergonic positive delta G = non-spontaneous, energy is consumed, endergonic what does enthalpy represent? what does it mean when it's positive vs negative? - delta H is change in enthalpy, which is the heat content of the reacting system. It reflects the number and ...
