Hey guys, I am a sophomore college student studying Aerospace Engineering and I am doing an experiment, and i ran into a little math problem that i can't seem to visualize properly.
I have a y-axis where which is a measure of pressure (from 0~200 bars), but expressed in voltages (1 to 5...
Hi, I was doing my fluid mechanics howework, and there was a question that I couln't quite answer.
Assuming that the integral of the axial momentum remains constant along the pipe cross section, the pressure drops uniformly along the pipe length. (Contrary to the Bernulli equation where the...
Hey guys, I'm a sophomore in a random engineering school, and just after I was finally getting used to the new school year, my professor decided to give us a little assignment about the 4th order Runge-Kutta methods... and I am totally stuck, and I just don't understand the concept at all...
Hi, I have to make a small presentation on how the phenomenon of gravity assist works. Basically, as we saw in Armageddon (I know, bad movie for scientific inspiration XD ) the two spaceships "slingshot" through the Moon, and attains higher speed, due to the Moon's own gravity.
I tried to use...
Hey, I am doing this physics project where we have to take pictures of various optical phenomena.
I was wondering what kind of phenomena can be photographed easily. One thing I thought of was total internal reflection, but I'm pretty much stuck on everything else. I need two different kinds...
Hi, I'm a grade 12 student aspiring to be a nanotechnology engineer.
I was wondering whether I need super strong math skills in that field. I'm good in math, but I'm not like sparkling brilliant in math. I get low~mid 90s on school, participate in math contests, etc, but I'm not the kind of...
Hi, I'm doing a chemistry project, where we have to build a drug. My group chose Clozaipne (or Clozaril), and we have trouble finding the actual bond angles for the compound. I swear, we looked at dozens and dozens of books, websites, encyclopedias, etc... no luck
I was wondering if you guys...
Hi, I'm a high school student thinking about going to Engineering.
I don't know which engineering field to choose, but I eventually chose nanotechnology engineering, partly because It is a new field since I thought about it the most. I plan to get an MBA afterwards to get into management...
We have a project that deals with ballistic glider designs. We've tested with designs that were of paper cones, weighted front and back using paper clips. However, our best achieved height-to-distance ratio was 1:1... we need it to at least 1:2.
We were wondering what other ballistic...
Homework Statement
Unknown: Pressure
Given:
V: 0.002 L
n: 0.019 mol
R: 8.31 (uh..any units here..?)
T: 498 K
Homework Equations
PV= nRT
The Attempt at a Solution
For some reason, the units don't cancel out when I attempt to reach the solution when I try to get the Pressure. So what are the...
omg Chem Titration help fast!
Ok so I'm a gr11 student who just had a titration exeriment.. and there are a couple of things that are really screwing me over!
Okay so we used an indicator, Phenolphthalein, more specifically, and when we stopped the titration when it turned light pink.
My...
Hey, I am a gr11 student and I just did a lab, and I do NOT understand a thing.
Ok, so I have hydrated Copper (II) sulfate, and basically I heated it up in a test tube in order to make it an anhydrous copper (II) sulfate compound
My question is:
-Is this a chemical or physical change...
omg...I am so pissed at myself
the antacid is a 2.0Mol/L HCI...
lolz thanks a bunch there bud.. It'll take me some time to process it through my Pentium-1 brain..=)
Nope.. sorry.. My "Chemistry manual" aint that rich in details... I am unsure of the chemical formula of the Antacid, and the moles of the substances used.
Basically, we are pouring either baking soda or antacids until the hydrochloric acids become neutral.. If the acid-nentrualizing ability...
