i should really start revising chem now.

Reversible reaction: a reaction that can be reversed. lol, band 6 here i come.

N omg stupid N....
Nitric Acid - Occurs when Oxides of Nitrogen dissolve into water.

 

[Leah.Midd]

Density
Mass per unit Volume: D=MV

 

[Casmira]

transuranic elements are elements of atomic mass past 92

 

[joeylike2hiphop]

think your too cool for school eat this

Chemistry: a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo
yeah yeah how do you like that! thats for transuranic and for elements
Science: knowledge as distinguished from ignorance or misunderstanding

 

[Leah.Midd]

hey guys...u play by adding a word and its definition that starts with the last letter of the last word used...just so u know

 

[MuffinMan]

gamma rays - a type of radiation emitted
relative charge = 0
relative mass = 0
penetrating power: high
type: electromagnetic radiation

 

[Leah.Midd]

Saturated Hydrocarbons: Hydrocarbons that contain only single bonds. They are also called alkanes or paraffin hydrocarbons.

 

[MuffinMan]

salt bridge - the purpose of the salt bridge is to allow migration of ions to occur

hehe revived ur thread dreamerish

Electronic Transition
The transfer of an electron from one energy level to another.

Electronic Transition
The transfer of an electron from one energy level to another.

neutron: sub-atomic particle which is found in the nucleus of an atom. has an overall charge of 0.

thanks hsc_Sucksss

Nitrate : Polyatomic anion of nitrogen and oxygen (NO₃^-1). Nitrates are oxidising agents and they exist as several interesting compounds. Ammonium nitrate is used time and time again to kill people cheaply and effectively (if confused, read more news!) as well as a fertiliser. Saltpeter (KNO3) is also a fertiliser and is the active ingredient in gunpowder.

electrolisys (sp?)
serperation of water into hydrogen and oxeygen molecules

 

[currysauce]

the carbon dioxide experiment is exothermic - hence heating soft drink causes CO2 to move into its gaseous form, reducing the acidity and thus is 'sharp' taste.

Cooling has the opposite effect.

Has 4 equilibrium equations

CO2 (g) <> CO2(aq)

CO2 + H2O <> H2CO3

H2CO3 (aq) <> HCO3- + H3O+

HCO3 - (aq) <> CO3 2- + H3O +

Electrolysis
currysauce read the game rules. Your term has to start with the last letter of the previous term. So it would have been s.

STP
(Standard temperature and pressure) 0°C and 1 atmosphere

Polyethene Common name is polyethylene, is a polymer created from repeating ethene monomers. Is produced in two forms in the petrochemical industry to be used as plastics, HDPE and LDPE.

LDPE due to increased branching forms a softer, more flexible plastic used in items such as plastic shopping bags is polymerised under high pressures. HDPE, however, is polymerised under lower pressures, which limits branching, forming straight chains leading to a harder, more rigid plastic used in item such as plastic toys.

Equilibrium: When a system is in equilibrium, the following properties remain the same:
- macroscopic properties
- temperature
- pressure
- concentration of reactants and products (but not necessarily equal)

 

[taxman]

Monoprotic Acid: An acid which contains only one hydrogen atom that can be ionised in an acid-base reaction. Therefore, one mole of a monoprotic acid will lend one mole of hydrogen ions when in an acid base reaction. Examples of these are HCl and CH3COOH.

 

[Leah.Midd]

Dilution rocess of reducing the concentration of a solute in solution, usually simply by mixing with more solvent

 

[princessj]

non-polar solvents: a liquid which consists of non-polar molecules. eg; hexane and tetracholride.
