Anymore answers are welcome and feel free to correct any mistakes. Thank you!
1.1 Kc=[product]/[Reactant 1][Reactant 2]
Unit- mol^-1dm^3
1.2 10.5 mol^-1dm^3
-Z-isomer (ignore my awful drawing, I tried doing it on my macbook)
-Equation for Cl free radical and ozone layer
Cl.+ O3 ---> ClO.+ O2
ClO.+ O3 ----> 2O2 + Cl.
-Drawing chloropentafluroethane
-Why those the molecule (one without Cl) not contribute to ozone depletion? Because doesn't have a C--Cl bond so no chlorine free radical is made.
-Why does greenhouse gases like Co2 absorb a lot IR? They have bonds that have high bond enthalpy
-Fluorine free radical and CH3CF2 (Check the formula I think it was that?)
Propagation Step 1: .F + CH3CF2 ----> .CH2CF2 + HF
Propagation Step 2: .CH2CF2 + F2 ---> CH2CF3 + .F
-Number of molecules + Avogadro constant question? 1.01 x 10^25
-Isooctane? Nomenclature- 2,2,4-trimethypentane
-Name how to separate Isooctane and octane and how?
Distillation and you heat the conical flask with temperature above 99 degrees so Isooctane compound vaporises but the other compound remains liquid. Condense in a cooling jacket.
-Oleic acid testing for unsaturated
Bromine water and Observation from orange to colourless
-Enthalpy change of Combustion of methanol- -307 kJmol^-1
-Why enthalpy change lower- neglecting the specific heat capacity of the calorimeter
-Uncertainty- 0.5/38*100= 1.31%
-Why Uncertainty of 0.5 is okay?
-Heat change for ethanol 11760 KJ maybe 11800KJ as it's in 3sf (I have a blurry memory about this one)
-Write the complete combustion of octane?
C8H18 + 12.5O2 -> 8CO2 + 9H2O
-Catalyst how it works
Lowers activation energy by providing an alternate route to a reaction
-How does NO and CO react?
2NO + CO ----> N2 + CO2
-Thin layer catalyst maybe because it's more cost effective and catalyst doesn't get used up during reaction so you don't need thick layer.
-Why are the two compound impossible to distinguish in precise mass spec?
Both has the same number of atoms for each element so same precise molecular mass.
-Infrared Radiation: O-H bond and 3230-3550 cm^-1
6 Marker: Alcohol (hydrogen bonds, permanent dipole dipole, van der waals) Aldehyde (permanent dipole dipole and van der waals) and alkane (van der waals)
7 Marker electrophilic addition
Outline Mechanism: arrow from double bon to H(delta plus) arrow from bond H---Br to Br)
Tertiary Carbonation ion is more stable than secondary carbocation because alkyl groups is electron releasing and stabilises the carbocation. So most stable carbocation is formed more. 3bromo is more stable than 2bromo.
-Excess find moles of both and magnesium has more moles than the other compound so more magnesium is needed for a the first compound to react.
-Graph- I drew it lower and slower because there's fewer moles of reactants. Should be lower and quicker according to other because the concentration increased.
-Acidified potassium dichromate display formula both ketone and carboxylic acid and equation
CH3CH(OH)CH2OH + 3[O] → CH3COCOOH + 2H2O
-Reflux Apparatus
-AntiBumping Granules
-What is the structure when not in excess?
Aldehyde and ketone one
Multiple Choices
-orange to red, aldehyde one with cho-
-Increase Temp- makes KC increase and yield increase C
-Last question multiple choice is C
-The C,H,O is B- ethanoic acid
-Nucleophilic Substitution
-Total Equilibrium moles 18
-The Cyclohexene general formula- CnH2n-2
-Cracking equation A
-Percentage yield is 86.6%
-Polymer question Which is the alkene- D
-Maxwell Graph- C That number of molecules of E>Ea
