I should say yes.

Homework Statement Will the following processes be spontaneous only at high temperatures, only at only temperatures, at all temperatures, or at no temperatures? 2CO(g)+O2(g)=2CO2(g) Delta(H)=-566kJ Homework EquationsThe Attempt at a Solution So i just need to figure out how to predict the...

I am in the section of Gibbs Energy for my chemistry course and in the textbook it says the system is at equilibrium at the boiling point, so deltaG=0, and deltaH=TdeltaS. I was just wondering if the system is always at equilibrium during any phase change, not just at its boiling point. Thanks!

Homework Statement Find all the points on the following curves that have the given slope: x=4cost y=4sint slope=1/2 Homework EquationsThe Attempt at a Solution Im not to sure what to do with this question.. I found dy/dx to be -cot(t) but I am not sure if that is even needed for this...

Problem solved! thank you guys so much for the help :)

Okay so i got the first question right, it was asking for the peak not the peak to peak. So for the second part about finding the frequency, I counted roughly 3.2 blocks as the period, so the frequency is just 1/period right? I am not sure what to put in for units though, i thought frequency was...

i think it means (and correct me if I am wrong) that there is 5 megavolts (5000000 volts) in every centimeter on the y-axis. So if the wave is 3.2 cm tall would you multiple 5mV by 3.2 to get the amplitude?
