*Actual yield of C₉H₈O₄: 0.11 g ± 5,8% *Theoretical yield of C₉H₈O₄: 0.25 g *Percent yield: (0.11/0.25)x100 = 43% ± 5,8% Have I done anything wrong when taking the percent error down? Help...=/

http://blog.wired.com/gadgets/2008/08/bell-labs-kills.html" Six Nobel-prize worthy research came from that lab, including the invention of the silicon transistor, and the laser! It was a business decision by the parent company but, I think it's a very myopic business decision to abandon...

I'm engaged in self-study with advanced undergraduate-level physics, currently focusing on Griffith's Electrodynamics text. I'm enjoying the problem sets in the text, but I sure would love to do some lab-work here at home. Does anyone know any good references for E&M labs or experiments?

I'm not a chem guy so I thought I'd ask here. To what extent can the labs be replaced with simulations? Computers have come a long way & nothing's changed so I figure I must be missing something.

Well, my chemistry teacher is extremely confusing, and wants us to create our own lab where we figure out the enthalpy changes in a chemical reaction. Is there are reaction out there that would give a considerable change in temperature, while using chemicals typically found in a high school? As...

I live in Houston and want to know where the labs are in Houston. There are labs in The Medical Center and NASA but I'm looking for physics. Are there any particle accelerators in Houston. Like Rice University, they have an atom smasher? I know we have alo of technology in Austin and Dallas...

Did Bush lie about "Iraqi weapons labs"? http://news.bbc.co.uk/2/hi/americas/4903592.stm The White House claims that Bush was speaking to the consensus of the intelligence reports to date. This particular report was only submitted two days before Bush made these statements, and it usually...

You probrbaly know that Texas is a hotspot for Science and Technology. I happen to be in Houston. While there's really no such thing as a Science company we do have labs. WHile there are a lot in The Medical center doing research in the biomedical fields I want to know are there any major...

What is the use of them? Today's research will not involve finding the velocity, acceleration, and position of a ball rolling down an inclined plane - and with such large experimental errors too. Furthermore, the labs at my school have a time limit of 3 hours so many students don't finish...

The Bates Laboratory and the Harvard Cyclotron lab use to be the only two labs in New England that I knew of which had high energy particle accelerators. The Harvard lab shut down and Bates lab will be shutting down in the future. There is a new lab in Boston at the Northeast Proton Therapy...

They say it would take 10 trillion trillion degrees and probably tons of pressure. Maybe more then the center of a red giant. Maybe more then a neutron star. Well if this is the way our universe began, were did the temperature and pressure come from. I am reading different stuff on how the...

Just got a copy of the Google Labs Aptitude Test (GLAT) as an insert in a magazine I get. Seems as if Google is actively recruiting since this is the second advertisement they have run in this mag, which typically only accepts classified ads. They add that if you score high enough – they'll...

hi pple were there any expts. of making clouds in a sustainable form in labs.has there been made such distinct pressures and temps. for clouds to exist in any of labs here on the ground?kindly reply.

"Mobile labs" aren't labs, it seems... It looks like the two supposed "mobile biological warfare labs" are, in fact, not. First, US/UK analysts disputed Bush et al's claims: http://query.nytimes.com/gst/abstract.html?res=F20E1EFD3C5D0C748CDDAF0894DB404482 . Tony Blair's government...

When you enter a chemistry lab, on the bench, there are some bottles containing chemicals, and some of these chemical bottles are tinted so that they have a dark brownish colour. My chemistry teacher had told the class that the dark colour is used to prevent light from getting to the...
