Homework Statement Compute and plot the compressibility factor (y) verses pressure (x) for the (1) Van der Waal’s (2) Redlich-Kwong and (3) Peng-Robinson equations of state. Compressibility Factor, Z = (P*v)/(R*T); where v is the specific volume (V/v). Data for n-Butane: T = 500 K; Tc = 425.2...

I thought that was where my mistake was! I try it again, thanks!

Now I'm stuck; do I have to find the change in temperature to find the state of water?

Okay, so far I think I balanced the equation (but I don't think I did it correctly.) 1 Al(s) + 3 Cl(l) -----> 1AlCl3 +H20 + energy I also calculate the amount of moles. (.371 mol Al, 1.777 mol Cl) Is this correct?

Hi, thanks for checking out this thread. I'm really having a problem with the question because I don't have any foundation. If you could, would you: Explain what exactly is going on? Is this an endothermic or exothermic reaction? What are colligative properties, and what do they have to...

Thank you Gad!

I see this in the fish market A LOT.

Its like a big balloon that could go POOF!

Hi. Sorry its been a while. lisab - Thanks its nice to meet you! dlgoff - I look forward to learning a lot! jtbell - Thank you! My favorite fish to look at is a tie between Angelfish and Pufferfish, and my favorite fish to eat is Salmon. Curious - No, I'm not NoodleDurh, but he (or she!)...

Hi, I'm new to this forum. I came here because I was told by a friend that the forums are great for getting help on classwork/homework. Aside from that, I came here to learn more about science. I always thought that science was about experiments and wearing white lab coats and growing long...
