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 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 ...

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 ...
