Homework Statement 60 L of N2 are collected over H2O at 40oC when atmospheric pressure is 760.00 torr. What is partial pressure of N2? Homework Equations PV=nRT Pt=P1+P2... Vapor pressure of H2O at 40oC:7.3590 KPa 760 torr=101.3 kPa 40oC=313oK The Attempt at a Solution PV-nRT...

My high school chemistry teacher tossed us the task and told us to figure it out ourselves. As far as I can understand, the trick is to supersaturate the solution, put a seed on a string and hope for the best. I'm just posting here to ask if anyone happens to know any good sites I might not have...

If nuclear waste is more radioactive than the nuclear fuel it is derived from, why can't it be used in a reactor?

My chemistry teacher taught it that way. Then how does the catalyst work?

If the catalyst is not part of the reaction and loses no chemical energy, where does it get the energy to speed up the reaction?

As someone who enjoys Design, Computer Programming, Chemistry and Physics, the archetypical path prescribed to me by career tests, guidance counsellors and parents is that I should become an engineer. However as final year looms near, I realize that I really have no idea what any engineer does...

Homework Statement Estimate the average force exerted by a shot-putter on a 7.0-kg shot if the shot is moved through a distance of 3.0m and is released with a speed of 10m/s . Homework Equations F=ma Maybe the Five Equations for constant acceleration? The Attempt at a Solution So my guess is...

My school had us complete course selection in two days so I made the rash decision of excluding biology. What engineering professions will this bar me from? Note: I will be taking French, Graphic design, Chemistry, Functions, Advanced functions and Physics. Is this a good group of courses for...

Well, this all makes sense theoretically but the fact that by adding more barriers to the current I help it flow makes no sense to me.

Why won't the first few loads have higher voltages? How is Vsource=V1=V2 possble? Sorry. I meant into one of the branches of the parallel circuit. I'm just asking why more loads in parallel circuits reduce Re of the whole circuit. In this case, the Re of the whole circuit. So you're...

I hear Google is an amazing workplace for Engineers dealing with computer science

I'm not condemning developing countries but with the advent of global outsourcing, manufacturing has all but died where I live and our "temporary worker" program has led to foreign workers taking over many sectors save the ones requiring interactions with the public. It's just frustrating you...

Even with the safety of nuclear reactors, the average consumer, as you say, would never stand for large scale implementation of nuclear near arable land or human settlements. Thus if many are built, they will probably be far from human settlements, leading to large loss of energy over the...

To clarify, By using a parallel circuit, more branches means each load has a higher voltage input, thus allowing a higher value for V in R=V/I. But that would mean parallel reduces resistance. What I'm asking is why if I have a parallel circuit and I fit another five light bulbs to one of the...

Why is it that introducing more loads in a parallel circuit decrease equivalent resistance? While we're on that topic, why is equivalent resistance, a changeable attribute, the resistance of a battery? And why is the voltage and Current in a series circuit the same across all loads, if the...
