    Physical Chemistry: Estimating ΔG of an Ideal Gas

    No, it does not. Does this equation apply? ΔG = nRTln(Pf/Pi) I found it in my notes but can't find it anywhere in the text.

    Physical Chemistry: Estimating ΔG of an Ideal Gas

    Homework Statement Estimate ΔG for the process where one mol of ideal gas is subjected to an increase in pressure from 1.00 atm to 11.0 atm at 25.0°C. Homework Equations ΔG=ΔH-TΔS ΔH=C(p,m)(Tf-Ti The Attempt at a Solution Seems straight forward, but it seems i am not given...

    Prove non adiabatic reversible expansion and ΔS

    Homework Statement One mole of a monatomic ideal gas is transformed from 0.00°C and 2.00 atm to -40.0°C and 0.400 atm. Show that this is NOT an adiabatic reversible expansion and calculate ΔS for the change. (Hint: you will need to consider a reversible path that includes a...

    Hot metal added to Water, Heat Capacity Problem

    Homework Statement A 100.0 g copper sample (specific heat 0.385 J/g K) at 100 C is added to 50.0 g of water at 26.5 C. What is the final temperature of the copper-water mixture? Homework Equations q = q(copper) + q(water) q = (heat capacity)(change in Temp.) q = (specific...

    Taylor Polynomial for f(x)=ln3x

    Homework Statement Find the Taylor Polynomial of degree 3 for the function f(x) = ln3x about a = 1/3Homework Equations NoneThe Attempt at a Solution I have found up to the fourth derivative of f(x) along with the values of the derivatives at x = 1/3. At this point i get Σ{(-1)kk!fk(1/3)}, but...

    Complex Numbers: nth Root Proof

    Haha, OK. I guess I need to get the question right before i can even attempt a solution :P. I'll post again once I make some progress, Thanks for clearing that up.

    Complex Numbers: nth Root Proof

    Homework Statement Really new to complex numbers so please forgive my ignorance. Prove that if the complex number z is an nth root of the real number x then the complex conjugate z (z with horizontal line on top) is also an nth root of x.Homework Equations i2=-1The Attempt at a Solution nsqr(z)...
