another e '-_-

excellent:

 

[Emma-Jayde]

EMF
The electrical potential produced by a chemical reaction, or electromotive force.

Almost made it electromotive force....But that was another e...

 

[lfc_reds2003]

F:

FFFree radical - an atom/compound with an unpaired electron
e.g chlorine radical which poses threats to OZOOOONE

 

[Dreamerish*~]

Lucas Heights: sydney's only nuclear reactor.

 

[Emma-Jayde]

Stoichoimetric
Refers to compounds or reactions in which the components are in fixed, whole-number ratios

C:

chem - is fun


CCPC - conquering chemistry preliminary course

 

[Jumbo Cactuar]

^^ Who says a free radical has to be an atom? Consider NO2!

well done aural sax, well done.

 

[Emma-Jayde]

Conjugate
An acid and base that are related by removing or adding a single hydrogen ion

Lol, I prefer Chemistry Contexts myself!

 

[lfc_reds2003]

E:

erroneous data - filtered by a line of best fit inresults , instead of averaging the exact figures.

something i rarely have


!

 

[Emma-Jayde]

Avogadro's Number
6.022 x 10²³ , the number of molecules in 1 mole of a substance

 

[Jumbo Cactuar]

^^ Sorry, me again. A proper 'line of best fit' includes the seemingly in error data. What you are refering to is fudging the numbers (and acedemic misconduct I might add)!

 

[gosh]

Roland Smith: author of CCPC and HSC CC books

I think he means drawing a line of best fit using the erraneous data, and using the line to predict results, which is perfectly viable in both HSC physics and chemistry. Possibly other subjects (not including maths) as well, but I don't do those so they don't matter!!!

Halogens
The column of elements from fluorine to astatine

 

[gosh]

spectrophotometer: a device used to measure levels of ozone in the atmosphere

 

[Emma-Jayde]

Red Cat: Mnemonic for reduction = cathode. Also An Ox for anode = oxidation

 

[gosh]

trace elements: elements that are required by living organisms in very small amounts

 

[lfc_reds2003]

thanks emma that was indeed what i inferred.!!

S:
Solution - solute + solvent

 

[Emma-Jayde]

Lol no problemo!

Nucleus
The core of an atom, containing protons and neutrons

 

[lfc_reds2003]

haha were back agian at it

S:

safety measures - remember eye protection ALWAYS!! wear gloves ALWAYS (we are told to even wear these while doing an exam....)
lol
