    Programs Struggling to decide on MSc following chemistry degree

    I'm not yet in a position to choose, hence my original reason for posting. Reaching a certain point in my education doesn't suddenly give me knowledge about the present state of different industries. Thanks anyway though. If anyone has experience in chemical engineering, forensic science...

    Programs Struggling to decide on MSc following chemistry degree

    Which part of my post makes it sound like I must be in high school? I'm nearing the end of a bachelor's degree in chemistry and on track to graduate with a 2:1. Whether I'm in high school or close to graduating university doesn't really have any bearing on my knowledge of the professions I'm...

    Programs Struggling to decide on MSc following chemistry degree

    I was hoping for a bit of advice about the options I'm considering, or if anyone knows of a good place I can ask the same question, that would also be appreciated. I'm considering a few different masters degrees but there isn't really one that I think I'd enjoy significantly more than the...

    Programs BSc Chemistry to MSc Chemical Engineering?

    I was just hoping for a bit of feedback on how realistic of a transition this would be. I'm nearing the end of an honors degree in chemistry and the job prospects look a bit dire. In my area there are lab technician jobs that require the applicant to have a degree, and the pay is less than what...

    Question about tenting in H NMR

    If tenting is observed in a 1H NMR spectrum, I understand what causes the tenting to occur, but can the presence of tenting allow anything be deduced about the proximity or arrangement of the protons responsible?

    Do you see a problem with the wording of this chemistry question?

    Okay thanks. I think I'm just interpreting "account for" in the wrong way.

    Do you see a problem with the wording of this chemistry question?

    I don't need help with the actual question, I just wanted to know if anyone else thinks there's an issue with this question of it it's just me. I've spoke to my tutor and he's confirmed what I need to do so I'm fine on that front, but I was curious if I'm just interpreting the wording...

    Science education vs general science knowledge

    This feels like a strange question but it's something I've often wondered so I was curious about other peoples opinions. I'm currently half way through a Chemistry degree and have been doing reasonably well. However I feel that the chemistry knowledge I have is only good for helping me answer...

    Confused about some details of potential difference

    I understand how to do calculations involving potential difference but I've never been able to find any information that helps me understand what is physically happening to cause it. My assumption is that for a PD to occur, there must be a build up of charge to cause the difference in...

    In the haber process why is the yield higher when liquid?

    Sorry, I really do appreciate your help, but I can't see how your reply provides an answer to this question that I posted the link to "What effect would there be on the position of equilibrium if the reaction was cooled to below ammonia's boiling point and ammonia collected as a liquid?" With...

    In the haber process why is the yield higher when liquid?

    I was doing this quiz and my question relates to question 5 on here. I may not have explained it very well http://www.bbc.co.uk/bitesize/quiz/q88871702

    In the haber process why is the yield higher when liquid?

    I know that setting the conditions so that the product is formed as a liquid will produce a higher yield in the manufacture of Ammonia, but why is this?

    Chemistry Struggling to decide between physics of chemistry for career prospects

    Thanks for the quick reply. To be honest I don't really know what I want, that's why I'm curious about which careers have good prospects and are in demand. There isn't a specific area that I'm interested in at the moment, I just want to collect some options that are likely to help me into a good...

    Chemistry Struggling to decide between physics of chemistry for career prospects

    I'm having trouble deciding between the two as I don't want to go into any specific field, my goal is just to be in a position to have a proper career. I don't know which subject has more prospects in the industry but I'll probably want to progress to a masters eventually and obviously will have...

    Very simple fraction simplification

    I feel stupid asking this, but I just can't see it. I need to simply this and I already know the answer, but I don't know why this is the answer. simplify 3p-3q 5p-5q My first reaction was to remove a factor of p-q but that would leave p-q(3-3) p-q(5-5) Which would be 0/0. I...

    Having trouble with simplifying things

    I know that part would just be 1 / √x but I can't do much more than that

    Having trouble with simplifying things

    Thanks, that does make it easier to deal with. I'm still having issues though, as the problem is I can't simply them. I know this is meant to be a basic step just to clean it up, but I just don't seem to be able to do it. Using your method of avoiding the quotient rule I came up with this (I...

    Having trouble with simplifying things

    This isn't about any specific problem, I'm just hoping for a bit of advice. I've been out of education for a long time and am now doing an OU degree. I've passed the first level with high marks but have been struggling in some of the maths. Basically, I've been doing calculus and the bit I'm...

    Simple trigonometry question

    I need to find the length AD. I thought that with the numbers given, and angle A worked out to being 70o there would be two different ways of working length AD out. I thought 8sin20 and 8cos70 would both be acceptable ways of calculating the length but they give different values. Where have I...

    W/Z Bosons & energy conservation

    I recall watching a documentary a while ago that explained the production of different force carriers. A bit that stuck in my head was that (if I remember correctly) W and Z bosons were able to violate the law of energy conservation. The energy to create these particles was apparently...

    Simple rearranging of an equation

    That makes sense now, think I need a bit more practice to make sure I pick things like that up. Thanks for explaining.

    Simple rearranging of an equation

    Could you give me a hint on the quicker way to do it please? I can't see it. The question doesn't require a minimal number of steps so I've already answered it the longer way, I'm just curious what I'm missing though.

    Simple rearranging of an equation

    I need to rearrange an equation to end up with something else. It's supposed to be an easy question but I can't see what I'm doing wrong. Posting the actual text here would mess up the formatting so I posted a screenshot to keep it neat, I hope that's okay. Have I done the entire thing wrong or...

    Think I need to find a way of exercising my brain

    I recently started a (self study) degree in physics and I'm enjoying it so far, but I feel like my brain has turned to mush. I've been out of education for a while but back when I was in school and college, I could pick new things up really easily, do big calculations in my head, etc. but I just...

    Units in a heat transferred calculation

    ohh I feel really stupid now. Any number to the zero power is equal to 1. I already knew this but mistakingly thought that the result of calculating kg0 would be 1kg, but the answer is literally just 1, isn't it? So the kg does actually cancel. I feel silly for not realising, thanks very much...

    Units in a heat transferred calculation

    I'm trying to do a calculation using: Heat transferred = mass x specific heat capacity x change in temperature q=mc∆T But the value I'm trying to calculate is the change in temperature so I've rearranged the equation to ∆T= q/mc I think the numbers and answer I have are correct, but the...

    Mass-energy equivalence and how it relates to the content of the universe

    Thanks for clarifying that. Is this process solely down to mass-energy conversion or does it relate to any other theorys? Like I said previously I've been reading about this theory but found very little mention of how it relates to the universe. Is it just not mentioned because it's obvious or...

    Mass-energy equivalence and how it relates to the content of the universe

    I've always been interested in Physics so have finally decided to do a Physics degree. I've been reading various things to help prepare myself and have just been reading about the laws of thermodynamics and mass-energy equivalence. As I'm reading through different articles about these subjects...
