Thats exothermic PFM. Though burning coal is a perfect example of an exothermic reaction

PurpleFistMixer

Ah yes.

How about melting ice then?

(I should really stop this tendency to guess crazily at answers)

Not a reaction as there is not chemical change.

Vinegar + baking soda in endothermic.

Iron oxide + charcoal (carbon) + heat = Iron + Carbon dioxide

Name four(4) methods of dating artifacts found

Erm, historical record?

do we actually have to know that for the JC? I thought the periodic table was in the maths tables.

Yes, but you are meant to know the first twenty anyway. Its handy to know the next 10.

Learn it by rhyme:

"Hydrogen, Helium.
Lithium, Beryllium.
Boron, Carbon.
Nitrogen, Oxygen, Flourine and Neon.

Sodium, Magnesium, Silicon, ....."

Gah. Even after all these years I can get most of the way, so ye should be able to get most of the way there.

Actually its:

"Hydrogen, Helium.
Lithium, Beryllium.
Boron, Carbon.
Nitrogen, Oxygen, Flourine and Neon.

Sodium, Magnesium.
Aluminium, Silicon.
Sulphur, Chlorine, Argon.

Potassium, Calcium....."

Do we not get a question? Or did I miss it?

Victor

Gimme a minute!

Describe the actions in the formation of the United Kingdom of Great Britain and Ireland.

JBoyle4eva

A lot of these are history, which I don't do.

Any chance another subject will come up?

PurpleFistMixer

Woah you get an option to do history?


And is that question in referring to the creation of Northern Ireland, older plantations kind of Act of Union things, or more recent history that I've not done yet?

Victor

United Kingdom of Great Britain and Ireland

The fundamental 3 steps in going from four countries to one.

Victor

OK under the "Acts of Union" passed in 1536 and 1543 Wales and England joined to form Britain, Scotland under the Act of Union 1707 joined to form [edit]the (United Kingdom of) [/edit] Great Britain. Ireland under the Act of Union 1800 joined to form the United Kingdom of Great Britain and Ireland.

When was the Emancipation Act?

The Fitz

It was 1829

PurpleFistMixer

Gonna ask a question?

JBoyle4eva

Define Respiration

declan_lgs

when O2 is used to make energy in the body cells, and releases CO2

explain the process of sexual reproduction

Raphael

When a man and a woman love each other very much.... =p

Seriously, the man releases semen which contains sperm and seminal fluid. The sperm enters the egg and fertilises it in the fallopean tubes. From there it travels down to the uterus and is implanted on the uterus wall (hopefully) it grows for 9 months, then comes out.

That's about the JC standard, I think. Open to the floor, cba thinking of a question

JBoyle4eva

What is 1 N in metric?

The Fitz

I never asked my question so here it is, whats the longest word in the english dictionary, 26 letter

Wait, isn't a newton a measure of force?

Take your pick. Yes I cheated blatantly, but what does this question have to do with the JC syllabus? O.o
Also that word site is really interesting... I now know plenty of useless trivia to ramble about in whatever exam I have next.

Now then, I've been contrary enough. Time to do music theory homework.
And if anyway wants a question...
Eh...
Name 3 features of glacial erosion. Now there's an easy one for you.

The Fitz

well its antidisestablishmentarianism for any1 who cares, people who are against people who are against government

Raphael

Actually, antidisestablishmentarianism refers specifically to people who were opposed to the seperation of church from state in britain

Newton is the unit of force, it can also be expressed as kg m s^-2. I can only assume you're referring to it in terms of weight, in which case 1 N weight = 0.1 kg

Define erosion

PurpleFistMixer

Erosion: The breaking down and removal of rocks due to moving water, glaciers or wind.

In history, there were 2 Treaties of Versailles (that I know of).
In regards to what were each of them made?

Victor

IIRC, following the Franco-Prussian war in 1870 and after the First World War. The second was a means of retribution / revenge for the first (among other things).

Both involved the transfer of Alsace & Lorraine between the countries and the payment of reparations.

Never heard of Geothermal, so I just left it there.

What is the difference between Thermoplastics and thermosetting plastics? (Covered in Metalwork)

Victor

JBoyle4eva wrote:

The use of hot groundwater or rock to heat water for the generation of electricity. Popular in volcanic regions and especially in Iceland. No CO2 produced, but the volcanic activity is likely to produce SO2.

What is the difference between Thermoplastics and thermosetting plastics? (Covered in Metalwork)

Also in science

Thermoplastics = will harden and soften with temperature, e.g. Polyethylene, PVC

thermosetting = won't harden and soften with temperature, e.g. Bakelite

[typos corrected]

JBoyle4eva

Well, not quite the right answer as given in metalwork.

Thremoplastics can be moulded and remoulded, whilst thermosetting plastics can be moulded ONCE!

Opening up the board for next question.

What was the "Quartering Act"?

PurpleFistMixer

Quartering Act - An act that required the American colonists of around 1765 to provide barracks and supplies to British troops, according to the internet. I was not aware.

area = 1/2 the base by the perpendicular height

area = 1/2absinC

at least i think so,
