I downloaded the handbook and only found dibromobenzophenone. Any other ideas please?

Hi, I have an organic chemistry assignment identifying an unknown sample. My tutor has asked for the properties (I can find all but refractive index) for vanillin and p-bromobenzophenone. I found that for Vanillin it is 1.555 but I know that it changes with temperature and I cannot find a...

thanks Mike H

my teacher also told me that fatty acids and amino acids would also burn. do these undergo a respiration reaction too?

thanks

thanks very much, I understand a lot better now. Also, are those 10 reactions available on the internet somewhere as my textbook doesn't cover it.

Hi there, I currently have an assignment on calorimetry. I chose to burn different kinds of potato chips and measure the energy that they produce. I am now in the process of writing up my report and I am struggling to understand the respiration reaction. The most common type of...

yeh i will just ask my teacher, i can get an answer that isn't wrong, just not sure if its the answer the teacher is looking for. Thanks for all your help you guys!

actually in our case b represents the decay factor, as a result the x is positive. However, as x increases b would get smaller (for the model i just said), meaning that when it is multiplied to a, the value of y would decrease as x increases.

yeh, what else am I missing?

is it just a?

but i don't understand why though.

Homework Statement In the standard model for exponential decay, y=ab^x , what does a represent and why? The Attempt at a Solution I know that a is the value of y when x=0, but I don't understand why this is the case. Any help would be appreciated, thanks.

Sorry my bad, I did allready understand that, just struggled to put it into words

I mean the center of the elipse. Let c equal the distance between the elipse center and a focus. a = the semi major axis b = semi minor c=sqrt(A^2 - b^2) Is that what you meant?
