O2-3.01 v/v%

N2-86.94 v/v%

CO2-10.05 v/v%

Calculate how much excess air was added

I am on the combined pill so have to take a break after 21 days. I usually take a break on Wednesdays, but I ended up taking it on that day. I didn't realise until Thursday and I dont know if I should carry on taking the pill or go on the break and take the pill of thursdays from now on.

Hello,

I'm studying Chemical engineering and one of our projects consists of designing and building a storage facility. We already have a Microsoft Visio design however, we wish do to a 3d animation of it which shows how the project actually works...as in showing the water flow and the pump.

Does anyone know any 3d animation services that can do this for you.....?

Or does anyone do it themselves?

In need of help....Thank you

Hello

I'm a Chemical engineering student, in my first year of chemical engineering and second year of university, I was previously studying extended engineering which is a preliminary year.

I'm looking to do a summer placement or summer internship this summer coming, and I have found some job options, however most of the jobs available are for students who are soon to finish.

Please may you help me, if you work in these sections or maybe know about certain engineering companies that take 1st year students

My first question is this:

1) The reaction of nitrogen with hydrogen to make ammonia has:

N2+3H2=2NH3 delta H=-92.2KJ

Find the value of change in internal energy if the reaction is carried out at a constant pressure of 40 atm and the volume is -1.12Litres.

2) Predict the standard enthalpy of reaction of:

2NO2=N2O4

at 100c from the following data

cp for NO2 = 37.2J/mol K

cp for N2O4 = 77.28 J/mol K

delta H NO2 = 33.18 KJ/mol

delta H N2O4 = 9.16 KJ/ mol

Please help thank you

looking for an answer to this question please help, I have worked some of it out not sure if the answer is right:

Calculate the standard enthalpy change for the following:

FeO(s) + CO (g) = Fe (s) + CO2 (g)

from the following data

R1) Fe2O3(s) + 3CO(g) = 2Fe(s) + 3CO2(g) delta H= -28.0 kj

R2) 3Fe2O3(s) + CO (g) = 2Fe3O4 +CO2 delta H = -59.0 k

R3) Fe3O4 (s) + CO (g) = 3FeO(s) + CO2 (g) delta H= 38.0 kj

Thank you, and please help :)

Hello I have just completed a course on Extended Engineering preliminary year, I'm now passing on to my Chemical engineering BEng(Hons) course and I'm if you may have any information on text books which are very good on this subject.

I have looked at thermodynamics for dummies and also engineering mathematics y K.A. Stroud and Dexter J. Booth. Do you have any information on books which will be good for the whole course instead of just one year?

Thank you

I'm a 19 year old university student. My bf moved here to the uk in feb and around that time we had problems in looking for a place for him to live since he could not get a guarentor. He was staying with me and I told my mother about it. Later on since I was having some problems in the place I was in we decided to move in together as it made it easier since I had a guarentor. My mother at first was against it, then when I spoke to her she accepted, however last night we had a huge arguement over this as she believes am not ready and because she is embarressed by it and what would people think if they found out. She also wants my student finance payments to go into her account however she is in a lot of debt and I know shes going to use the money to pay that off instead of for me. Ever since I got into university she has complained and complained that I need to give her money and also lies that she is in debt because she 'pays my uni and accomodation' to my family so they contact me blaming me for everything.

What should I do? Am tired of arguing, she wants me to tell her everything and wants us to have an open relationship but how can we? I want to stay with my bf we love each other very much he is 22.

Please help I'm trying to look for the answer and solution..Thank you

1. A wheel rotates with an angular velocity of 1.1 rad/s. If the moment of inertia of the wheel is 0.7 kg.m^2.

i. calculate the torque needed to accelerate the wheel to an angular velocity of 3.2 rad/s in a time of 18.4s

ii. determine the angle through which the wheel turns during the 18.4s acceleration stage.

iii. a sound source has a power of 6.8w. determine the intensity of the sound at a distance of 30m from the source.

Thank you, please can you help me....

Basically I live at Teesside house campuslifestyle in middlesbrough, I have had some problems with one of my roommates, as in she has been 'bullying' me in a way. she would bang on my door in the middle of night and on the walls, and would also put things in my food including bleach, nail varnish and spray deodrant on it. my boyfriend stayed with me, and before he did i asked the permission of everyone in the house if he could and they all agreed. however, she made a complaint about him, and another boy who was also living here with his girlfriend. one night i was cooking and she came in a put a sign up saying 'no more chicken' and told me that everyone was sick and tired of me cooking. I thought enough was enough, and went to complain about her with my boyfriend and the two other people. campuslifestyle held a meeting for us and the girl and she denied everything in front of us. I told campus that i wanted to move, and if there was any other rooms available however she said not until august, so i decided to look elsewhere for a one bedroom house, one for me and one for my boyfriend as we were not going to move in together. i emailed campus and one of the lettings person said that i could not move because my contract ends in august, she knows about the situation as she was the one the interviewed us. She was very rude, and told lies not just to me but to my mother saying that nothing had happened in the flat to her. I told her that my mother wants to take legal actions, and she sad she would agree but then pursue for the money of the rent later on in the future. I no longer feel safe here at teesside house, and she had the courage to blame it on my mum signing the contract with them, saying that she could have signed on for 6 months not a year. and also blamed it on my boyfriend saying that all i want to do is live with him. i have evidence that the girl did these things, and i want out of teesside house now.

please what can i do, what legal actions should i take?

I've been having a serious problem with one of my roommates, I have not done anything to this person seriously, i keep myself to myself and just focus on my studies, i don't speak to anyone about my problems and don't comment about anyone else. for quite a while this person has banged on my door at late hours, put signs up directed to me and has been cruel. i have tried speaking to the person however, they were just exteremly sarcastic and laughed in my face.

i have spoken to the owners of this private student accomidation making a complaint but not much has been done as she just continues.

what i want to sue the person for is for the fact that she poisoned my food with bleach, at the time i did not say anything because my granddad had past away and everyone in the house knew about it. I have witnesses who heard her speaking to another roommate, laughing and saying that she had done that, also i had spoken to some roomates at the time saying the the food did not taste right. the next day i vommited, this happened around oct-nov. What can i do, i need help and advice.

I'm very unsure

I really want to do a mathematical course for a year, but I can't seem to find the right places. Please can you help me

We have finally received our results!

I could have done better and I know I could have, however I went through a time of heartache in my family, loss, depression, even terrible things that are hard to talk about.

As all this was going on I had my exams to think about, however it was hard to focus and I failed the subject that I most love 'Chemistry'. I do not want to take up religious ethics because, Chemistry is where my heart lies, my teachers told me that it would be for the best if I did RE, but I know I can do Chemistry, am better at it then RE and not just that but, its my passion.

Please how can I prove to my teachers that this if for me, and beg them to let me do it (they know of the problems). Someone please help me
