Q

Outline what happen in blast furnace

A 
Iron ore, coke, limestone in
Oxygen then in, 1200-1300 degree celcius
Carbon in coke react with o2 for CO2 then react with coke for CO
CO displace Iron and Iron formed
Slag is formed
And waste gases are removed

16
Q

cation

A

positive ion

17
Q

anode

A

positive electrode, oxidises anion

18
Q

cathode

A

negative electrode, reduces cation

19
Q

electrolysis of Francium Chloride

A

1) FrCl is molten
2) Fr to cathode as it is Fr+, reduced: Fr+ + e- → Fr
3) Cl to anode as it is Cl-, Oxidised: 2Cl- → CL2 + 2e-
3) Done

20
Q

Aluminium electrolysis

A

bauxite with cryolite → lower Melting point as bauxite too high.
Graphite Electrode replaced of Oxygen reacts with it to form CO2
Electrolyte is Molten Al2O3

21
Q

Aqueous Electrolysis

A

H2O dissociates when something is dissolved in it.
H20 equilibrium sign H+ + OH-
in Cathode: Hydrogen compete with metal, if metal more reactive than H2 formed and vice verse
same in cathode but OH is into O2 not H20.
And it is halogen or not.

22
Q

Hydrocarbon

A

Compound with only Hydrogen and carbon

23
Q

inter molecular forces

A

Forced between molecules. More larger molecule, more stronger Intermolecular forces and more energy needed to break

24
Q

Crude oil/Fractional distillation

A

Crude oil-Mixture of hydrocarbons with different chain lengths.
Fractional distillation used to separate it.
1)Evaporate Crude oil
2)Enters Fractionating coloumn
3)Heat from bottom for temperature gradient
4)When a fraction of it reaches an area of its boiling point, it condenses.
5)High Boiling points are near the bottom.

25
Q

Covalent bonding

A

sharing of electrion between non metals

26
Q

Cracking

A

breaking long molecule into short ones (Alkane and alkene)
Also 2 types:
Thermal-750 degree celcius and 70 atm pressure.
Catalytic-500 degree and zeolite catalyst-industry prefere it of lower temperature

27
Q

Practical of cracking

A

1) put mineral wool of paraffin in bottom of test tube
2) Place catalyst in middle
3) Heat
4) Gas form
5) Collect in test tube
6) Take out the delivery tube for no suckback-H20 into tube and cause to crack

Tubes:
1-Air
2-Air
3-Camping gas
4-Ignite for Flammable gas
5-BrH20 test for alkene
6-Potassium permangenate for Alkene.
28
Q

Alkanes

A 
saturated hydrocarbon with formula CnH2n+1, single bond. A homologous series.
Methane-CH4
ETHANE-C2H6
PROPANE-C38
BUTANE-C4H10
and more
29
Q

Alkenes

A

unsaturated, double carbon bonds. Formula of Cnh2n. A Homologous series.
ETHENE-C2H4
PROPENE-C3H6
BUTENE-C4H8
PROPENE-C5H10
And more.
They have addition reactions-reactions which open up their double bond.

like hydrogenation into Alkane:Alkene+h2→Alkane.
H20 for Alcholol. Reacts with halogens like ethene and bromine for dibromoethene. Also turns BrH20 Colourless.

Also can react to form addition polymers when reacting in Addition Polymerisation

30
Q

Alchohol

A 
-OH- functional group.
METHANOL-CH3OH
ETHANOL-C2H5OH
PROPANOL-C3H7OH
BUTANOL-C4H9OH
Goes under combustion, also oxidises into Carboxylic Acids. And also used as solvent and fuels.
31
Q

Carboxylic Acids

A 
-COOH- functional group
METHANOIC ACID-HCOOH
ETHANOIC ACID-CH3COOH
PROPANOIC ACID-C2H5COOH
BUTANOIC ACID-C3H7COOH

They react with metal carbonates to form metal anoates like methanoate or ethanoate.
They are weak acids.

32
Q

Esters

A

-COO- functional group
Carboxylic acid+Alcohol forms with with acid catalyst like Sulfuric acid.
They form things like Ethyl Ethanoate or Methyl Methanoate or Butyl Propanoate

33
Q

Zacian

A

A steel/Fairy type pokémon who is broken with the ability intrepid sword and with insane power and speed.
