I can fix the electronics' settings but I was wondering more about the water system setup. Correct me if I am wrong, but basically using the height difference you would know what a difference in pressure should be and then you can check what the reading is. If I raise the water container (or...

It's a differential pressure sensor. MPX5100DP by Freescale is the actual sensor being used.

So I have built an incomplete rig to measure the pressure of a setup I have in a lab. The pressure sensor is hooked up to electronics and I have not used the electronics (basic National Instruments electronics) and am not sure if did the wiring correctly. The setup I have basically has a bottle...

You can do NMR Spectronomy for a good result to see if it is Aromatic. I understand now that C and O have a pi bond because they have a double bond between each other. I just wasn't thinking because it was late. So then there are pi bonds on all the Carbons, creating a continuous lobed...

I understand the rules of aromaticity, but I do not understand why Tropolone is aromatic. The main reason is because I thought all the atoms in the ring have to have p-orbitals. How does the C connected the oxygen with a double bond have a p-orbital? Have to do with the resonance (that's my main...

Thank you DDTea.

It has high temperature (400°C) and Al2O3 is a dehydration agent. How does temperature affect the reaction? Why is Aluminium Oxide used? What does it do?

I am reading the beginning of the chapter about Conjugated Unsaturated Systems and it is discussing relative stability of the allylic radical in comparison with other compounds. This is what it tells me for the DH°: Allylic Radical - 369 kJ*mol-1 3° Radical - 400 kJ*mol-1 2° Radical - 413...

Thanks tiny-tim for your advice and help! In the end I had converted 100 pF to 1E-9 F rather than 1E-10 so my answer was off by one degree (30 mV vs 3 mV). And I thought the radians would "disappear" somehow, so thanks again.

Homework Statement A resistor with resistance R and a capacitor with capacitance C are connected in series to an AC voltage source. The time-dependent voltage across the capacitor is given by V_{C}(t) = V_{C_0} sin(\omega*t). (there are no superscripts, but they show up as super for me, though...

I re-looked at it, and noticed that there would be a carbon missing if the answer was what I put. I would change my answer so that the middle Carbon furthest from benzene would have another carbon. Does this seem more reasonable?

Homework Statement (a) Draw the product that would be formed. (b) Provide a brief explanation for this and provide a couple of sentences and key mechanistic step(s) to illustrate your reasoning The Attempt at a Solution Here is my reasoning and what I believe the reaction would...

Homework Statement Consider two macroscopic containers separated by an insulating wall, which however has a circular hole of a few nanometers radius and negligible thickness. The containers (1 and 2) enclose aqueous solutions of a polymeric chain molecules (e.g. a DNA or protein). These often...

I can't edit the problem, but the x-axis (\hat{i}) is left-right and the y-axis (\hat{j}) would be up-down, if I am not mistaken. The origin would then be at the -10nC.

Homework Statement What is the direction of the force \vec{F} on the -10 nC charge in the figure? Give your answer as an angle measured cw from the +x-axis. Problem 26.39 in Physics for Scientists and Engineers Second Edition by Knight Magnitude of the force is 4.3E-3 N Homework Equations As...
