What is the difference between ΔG and ΔG°? When does ΔG = ΔG°?
answer #63 by using #61
63) Use standard free energies of formation to calculate ΔG° at 25°C for each reaction in Problem 61. How do the values of AG° calcu- lated this way compare to those calculated from ΔΗ' and AS? Which of the two methods could be used to determine how ΔG changes with temperature? İN or each reaction, calculate Δ Hon, Δ-mn, and ΔGon at 25°C and state whether the reaction is spontaneous. If the reaction is not...

2. What is the difference between MyClass implements Comparable and MyClass mplements Comparable<MyClass>? 3. When using generics, we saw that the syntax is MyClass<AnyType extends Comparable <AnyType> a. When do we use extends instead of implements? b. Why do we need the second AnyType in that declaration?

need the answer to the question:
calculate the difference in energy between the axial and equatorial
conformations.
VII. Calculations of the Conformations of Substituted Cyclohexanes In this exercise, you will examine the conformational equilibrium between axial and equatorial methylcyclohexane. Begin by drawing a methylcyclohexane using ChemDraw. Don't forget about the rings shown at the bottom of the toolbar. Chem3D will automatically put the methyl group in the low energy equatorial conformation. Minimize the energy using the calculations) menu. Select MM2...
What is the difference between a histogram and bar chart? (Explain in at least 4 sentences) What is the difference between a pie chart (circle) and a bar graph? When should you use a pie chart instead of a bar chart? (Answer in at least 5 sentences)
I. (a) Calculate the Gibbs free energy change ΔG and the entropy change ΔS when 1.0 L of CO2 and 9.0 L of N2, initially separated and both at 2.0 atm, are allowed to form a homogeneous mixture at a constant temperature of 0°C and with the final (total) pressure still 2.0 atm. decreases the sign should be negative). at this temperature, that is, μ-μ (b) What is the change in the chemical potential for CO2 between the initial and...
What is the difference between specific heat and heat capacity? What are the units for these two quantities? 5. Calculate the standard enthalpy of this reaction, based on the following ΔΗ? values for each substance in the reaction: 6, NH2N,04(g)6NO(g) 2H200) N20(g) 9.66 kJ/mol N2H(0) NO(g) H0() -2858 kJ/mol 50.4 kJ/mol 90.4 kJ/mol
What is the difference between an absolute and a relative link? What are the advantages and disadvantages of using each type? Can you give an example of how you would use an absolute link and a relative link on a website? I look forward to your reply.
What is the value of ΔG o in kJ at 25 oC for the reaction between the pair: Cu(s) and Cr3+(aq) to give Cr(s) and Cu2+(aq) Use the reduction potentials for Cr3+(aq) is -0.74 V and for Cu2+(aq) is +0.34 V. For these questions, I keep getting a negative answer. The correct answer to this question is 6.3E2, and I put -6.3E2. Why is it a positive number? Isn't the reaction spontaneous?
