Specific Heat :The amount of heat required to raise the temperature of one gram of substance one degree Celsius.

 

[Emma-Jayde]

ternary compound: a compound containing three different elements

 

[Dreamerish*~]

Dispersion forces: The weakest of all intermolecular forces. It is formed when temporary dipoles are formed between atoms.

States of matter Solid, liquid, and gas

Ooooh I'm headed straight for a UAI of 100 with that one!

Oh my god! Markmooks in my chemistry thread!

R-O•: Free radical, generated during initiation of the polymerisation process.

RATE OF REACTION

The rate (or speed) at which a reaction occurs depends on several factors:

1) temperature: the higher the temperature, the faster the reaction is bec ause the particles are moving with greater energies
2) particle size: the smaller the particles involved, the greater is the surface area where the reaction can take place and the faster is the reaction.
3) concentration: the more concentrated a solution (or the higher the pressure of a gas) the gaster a reaction will occur. This is because there are more particlesin a given volume to react.
4) catalysts: these change the rate by providing an alternative reaction pathway along which the reaction can occur.

you managed to post just before me lol

octane rating:

petrol and air mixtures have to explode at exactly the correct moment in an internal combustion engine. if the wrong kind of fuel is used ignition of the mixture can ocur before it should. this leads to knowcking. the octane rating (or octane number) of a petrol is a measure of the anti-knock qualities of the fuel.

Luigi Galvani : (1737-1798) Proposed the theory of animal electricity after his famous frog legs experiment. Similar experiments were performed on dead fellons gave rise to the story of Dr. Frankenstein. Galvanization is the process of coating metals by the work of an electric current as well as treatment with electric shock.

Incomplete combustion: Occurs in petroleum fueled motor vehicles. Incomplete combustion usually occurs due to insufficient oxygen content or out of tune engines. The products of incomplete combustion consist of carbon monoxide (CO) and soot among others.

 

[Dreamerish*~]

Neutron Bombardment: Accelerating a neutron and bombarding an atom with it, causing the atom to absorb the neutron and become unstable.

 

[Emma-Jayde]

Theoretical yield: the calculated yield of a reaction based on the assumptions that there is only one reaction involved, that all the reactant is converted into product, and all the product is collected

Hey Dreamerish, ewigkeit is eternity right?

 

[joeylike2hiphop]

d....d.....

d urh d.....hmmmmm
Dimer: two linked monomers!!

 

[Dreamerish*~]

Radioisotope: An isotope of an element which emits radiation. Duh.

 

[The_highwayman]

ESTER: Sweet-smelling oily substances produced in a condensation reaction between and alkanol and alkanoic acid

 

[Dreamerish*~]

Refluxing: Process involved during esterification. Vapours are condensed by passing cool water through the refluxing tube in order to prevent loss of products.

 

[The_highwayman]

GLASS: a HIGHLY viscous liquid made from a combination of 'melted' silicon dioxide with other chemicals

 

[taxman]

Systematic name: The name for compunds set out by IUPAC. For example, the systematic name for poly(ethylene) is poly(ethene), or poly(vinyl chloride)'s systematic name is poly(chloro ethene.)

 

[The_highwayman]

ENTHALPY: A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied by the pressure exerted on it by its surroundings.

Ok. Taking the rule of the 'y's from the last game...Where we ended up making it so that you take the 2nd last letter. Because all we could come up with were yeild, yttrium and yeast, and we've already had all those.

So...p

partial pressure: the pressure exerted by an individual gas in a mixture of gases.
