I did an experiment in my Chem II class that required finding the equilibrium constant for this reaction
Fe3+ + SCN- ->Fe(SCN)2+
For the experiment, I had to use a calibration curve and Beer's law. How do I know that the calibration curve obeys Beer's law? I know that it would have to be a...
Yea it would be. Technically I haven't learned that yet so it wouldn't be appropriate to use future processes.
However, even after obtaining the equation you gave me earlier, I still don't know what to do. I don't think I can pull out an (x+h) but that's the only thing I can think of doing...
Problem:
Assume that f has a derivative everywhere. Set g(x)=xf(x). Using the definition of the derivative, show that g has a derivative and that g'(x)=f(x)+xf'(x).
What I know:
I know the definition of the derivative is [f(x+h)-f(x)]/h. I don't know how to plug it in and solve it though. I...
Homework Statement
A 29000-kg railroad freight car collides with a stationary caboose car with brakes released. They couple together, and 10 percent of the initial kinetic energy is dissipated as heat, sound, vibrations, and so on. What is the mass of the caboose?
This is the equation that...
