(1a)
Hydrocarbon;This is a compound
consisting of
carbon and hydrogen only
(1b)
-High temperature -Presence of catalyst
(1c)
Oxidation is defined as the loss
of electrons
(1d)
-The object is placed at the cathode
-The electrolyte to be used
should contain the
electroplating metal
(1e)
i)Pent-2-ene ii)Butanoic acid
(1f)
Dalton's law of partial pressure
states that the
total pressure of a mixture of a
gases equals to sum of individual pressure
(1g)
(i)-They have improved
mechanical properties
-They are better in service
(ii)-Carbon -Iron
(1h)
(i)Electrovalent bond
(ii)Mettalic bond
(iii)Electrovalent bond
(1i) (i)Isomers are compounds having
the same
molecular formular but different
structural
formular
(ii)Because it is inert and have a completely
filled orbitals
(1j)
Galvanic cells are cells that
convert electrical
energy to chemical energy 3ai)
CH3CH=CHCH# is alkene
CH3COOCH3 is alkanoate
CH3CH(OH)CH2CH3 is alkanol
CH3(CH2)2CH3 is alkane
ii) -But-2-ene
-ethyl ethanoate
-Butane
-But-2-ol
iii)CH3(CH2)2<CH3CH=CHCH3<CH3COOCH2CH3<CH3CH
(OH)CH2CH3 2bi)
-Ultraviolet light
ii)
C2H6+Cl2->C2H5Cl+HCl
iii)
-C2H5Cl+Cl2->C2H4Cl2+HCl -C2H4Cl2+Cl2->C2H3Cl3+HCl
-C2H3Cl3+Cl2->C2H2Cl4+HCl
-C2H2Cl4+Cl4+Cl2->C2HCl5+HCl

iv)
Hexachloroethane 4ai)
Allotropy is the existence of a
compound in
two or more physical states
ii)
-Diamond is crystalline bond -Graphite is covalent bond iii)
-Diamond is hard because it
consist of fused
carbon whereas graphite
consists of weak
intermolecular forces -This is because graphite
consists of mobile
electrons in the crystal lattice
4bi)
-Excess of oxygen
-Limited supply of air ii)
C(s)+O2(g)->CO2(g)
2C(s)+O2(g)->2CO(g) iii)
-Carbon(iv)Oxide
-Carbon(ii)oxide
4ci) -Pb(NO3)2+2NaCl->2NaNO3+PbCl2
ii) -Molar mass of
PbCl2=207+(35.5*2)
=207+71=278g/mol
2g will produce 1g of PbCl2
1g will produce 1/2*5.56 278g will produce 1/2*5.56
=0.019
