Chemistry Equations

Production of oxygen O2
Hydrogen peroxide ---manganese dioxide (catalyst)---> water + oxygen.
2H2O2 ---MnO2---> 2H2O + O2
Proof of oxygen: relights a glowing splint.

Carbon (charcoal) burned in oxygen:
C + O2 ---> CO2 : This is an acidic oxide.

Magnesium burned in oxygen:
2Mg + O2 ---> 2MgO : This is a basic oxide.

Production of CO2, carbon dioxide (denser than air, can be poured)
Calcium Carbonate (marble chips) + Hydrochloric acid ---> Calcium chloride + water + carbon dioxide
CaCO3 + 2Hcl ---> CaCl2 + H2O + CO2
Proof: quenches a lighted splint.

Limewater + carbon dioxide ---> Chalk + Water
Ca(OH)2 + CO2 --->CaCO3 +H2O

Carbon dioxide + water ---> Carbonic acid (acid rain)
CO2 + H2O ---> H2CO3

Production of hydrogen, H2 (colourless, odourless, highly reactive gas)
Zinc + Hydrochloric acid = Zinc chloride + Hydrogen
Zn + 2HCl = ZnCl2 + H2
Proof of hydrogen: Popping noise with a lighted splint.

Acid Rain:
Carbon dioxide in air dissolves in rainwater
CO2 + H2O ---> H2CO3 (carbonic acid)

Sulfur dioxide (SO2) from factories and cars burning fossil fuels SO2 then dissolves into rainwater
SO2 + H2O ---> H2SO3 (sulfurous acid)

Fossil fuels are hydrocarbons containing hydrogen and carbon.

Rust:
Iron + oxygen + water = iron oxide

Ah Dylan do you have a book? Is there anything else you're missing? I'm just doing stuff I think will come up I'm probably way off but I feel more proud thinking that this might actually come up on the exam rather than pointless stuff...

Wow, just looking into this thread for the first time. There are some fantastic notes here, there are all so long.

I didn't use any of them but still, well done to anyone who added anything to this thread. It's some achievement.

I was just about to make a new thread for this stuff. I'm a bit OCD, but this one will do.

I'll try and post up some of my revision notes sometime. They're not really detailed though - just a review of the topic.

Yeh, going to start studying for the exams we have the week after next. I will post some up here too.

Freagra Samplach don "Anseo i lar an gleanna"
I thought of this off the top of my head the other day

TEAMA : Stair na hEireann

Rinne mé staidear ar an dán "Anseo i lar an gleanna". Scriobh Sean Mac Fheorais ag an dán seo.Roghnaigh mé an teama Stair na hEireann mar, I mo thuairim, Tá a lán rudaí sa dán seo madir leis an stair na hEireann, Ar dtús, Insítear sinn go bhfuil "Bhí an taifreann léite is gach rud deanta" agus gur chuala na daoine an glao ag teacht i a dtreo, ceapann na daoine go bhfuil na capaill ach tá siad mícheart, Is é na saighduirí sasanaigh ag teach chun an sagart a mharú.
Agus Tá an seanfhear ag dul go dtí an sagart agus míníonn sé cónas atá sé sean agus go bhfuil an sagart óg, iarrann an seanfear ag an tsagart má tá cead ag an seanfear go bhfuil eadaí a mhalartú leis an seanfhear, insíonn an seanfear an sagart go bhfuill gá agat chun dul i bhfolach roinnt áit slán saibhailté agus ansin, Cuardaíonn na saighduirí an seanfhear sna eadaí sagairt agus crochann na saighduirí an seanfhear an crann caol ard.
Usáideann an filé friotal shimplí agus iomanna beo chun teama a chur ós ár gcomhair. Tugann an filé cuntas mhaith dúinn madir leis an stair na Éireann, Míníonn sé cónas a bhí an saol in Éireann an dáinsearach don sagairt agus nach raibh cead ag na sagairt chun aifreann a rá.

Please excuse any grammatical errors as we haven't done declensions or anything of the sort yet

Also this isn't as such a sample answer but one I got an A for on the Scéim Marcála

Sample Answer for English[/B]

Question : From a play you have studied choose a scene that highlights the qualities of the principal character, Explain how these qualities are revealed in this scene.(30)
Once again, Not exactly a Sample answer just one I got an A for

The play I have studied is Julius Caesar by the English playwright William Shakespeare, Brutus is the principal character whos qualities are highlighted in Act II Scene I. In this scene we are shown Brutus with a troubled mind, much similar to a battlefield, this is shown when Brutus explains how he is unable to sleep,"I would it were my fault to sleep so soundly". This conveys how Brutus would desire to be the one always sleeping instead of Lucius.

Brutus also has a great love for Rome as is shown when he expresses his desire to kill the spirit of Caesar and leave the man untouched,"O, that we then could come by Caesars spirit and not dismember Caesar" This highlights the fact that he has no desire to spill Caesars blood but if it stops him from essentially destroying Rome, Brutus is willing to do it, In a way, that speech highlights Brutus' willingness to do whatever is needed to keep Rome glorious and free of corruption and tyrancy.

Brutus is an Idealist,where everything is perfect and he has a belief that there are certain ways of doing things et cetera. Cassius however, is a realist, he sees the world the way it is,not in the idealistic view of Brutus, this difference is most evident when they talk about killing Mark Antony, Brutus is clearly disgusted by the idea of more bloodshed because Brutus thinks that he isn't killing the man Caesar but only his ambition, so as far as Brutus is concerned he isn't killing anyone, whereas Cassius insists on killing Mark Antony as he thinks he will betray them later on, but Brutus thinks differently and this conveys his one flaw, he is a bad judge of character, much like Mark Antony himself,Brutus thinks he will be not trouble at all ass "he is given to sports, to wildness and much company". Brutus dismisses him as nothing more than a playboy.

We are shown Brutus is also very Honourable and honest, much unlike Cassius who could be described as a "Shrewd Contriver", much like his description of Mark Antony, but it is very ironic when Cassius suggests swearing an oath, "Let us swear our resolution" and Brutus totally disagrees saying "Swear Cowards, priests and men cautelous" but Cassius is actually quite cautelous and sneaky in himself, this could imply that Brutus is calling Cassius cautelous and knows he only has his personal interests at heart but generally we are given the view that Brutus is too blinded by Idealism to see Cassius' and the other conspirators ideals.

Brutus is also very naive not to see the rest of the conspirators ideals. Brutus comes across, finally as a well respected man by the conspirators,"but what of Cicero shall we sound him?", and Brutus replies "O, Name him not" and then all the conspirators instantly comply with all and any of Brutus' demands.
Any tips/constructive criticism is appreciated :P

The Periodic Table arranges the elements in order of increasing atomic number.

Atomic Number: The number of protons in the nucleus of an atom of an element.

Groups/Families - Vertical column.

All elements in a group are chemically similar.
All elements in a group have the same number of electrons in their outermost shell.

Group 1 - The Alkali Metals.
Group 2 - The Alkaline Earth Metals.
Group 7 - The Halogens.
Group 8 - The Noble Gases.

Period - Horizontal Row. (n=1, n=2, etc.)

All the elements in a period have the same number of electron shells.

Non-Metals are on the right.
Metals are on the left and center.

the notes thread is getting very big, but i was thinking, we should make specialised threads for evry subject and post notes on each one instead of having on hugeeee one, because i dont know if it was just me but the notes thread is amazingly helpful, but quite confusing if you are looking for something in particular,
so,
happy noting!

looking through this thread for the first time, there are some brilliant notes up here already so thanks to everybody who contributed.

Hopefully more notes will be added!!!!!!

While it would be a good idea to have a separate thread for each subject, it would just clog up the forum.
