Dear JohnRC,
Thanks for your reply. I appreciate it.
You were right: in my previous post, I meant NH_3 instead of NH_2.
(1) So, the reaction should be rather:
3 N_2H_4 \rightarrow 4 NH_3 + N_2
1.2 NH_3 \rightarrow 0.6 N_2 + 1.8 H_2 (30% of 4 NH_3 decomposes).
Since the...
Dear all,
Homework Statement
For practice, I'm trying to solve an exercise I've found on the Internet. A screen shot of it is attached. I would like to be sure about my approach, especially when it comes to question 2.
Let's say, for the sake of simplification, that the reaction is as...
Dear All,
I computed an integral that looks like erf(x) without problem: \int_{-\infty}^{+\infty} e^{-t^2} dt = \int_{-\infty}^{0} e^{-t^2} dt + \int_{0}^{+\infty} e^{-t^2} dt = \frac{\sqrt{\pi}}{2} [-erf(-\infty)+erf(+\infty)] = \frac{\sqrt{\pi}}{2} [-(-1)+1] = \sqrt{\pi}.
However, what...
