(6a)
Total students= 52
No of boys = 1/3*16 = 16/3
No of girls = 1/4*16=4
(6b)
Using Fn= ar(power)n-1
F3=ar(power)3-1= ar
a + ar(power)2 = 40 ------eqn(1)
F4/F6 = 1/4 --> ar(power)3/ar(power)5=
1/4.
1/r(power)2=1/4.
r(power)2= 4.
r = sqrt(4).
r=2.
(i.) Common ratio(r)= 2
(ii) Substitute r = 2 into eqn(1)
a + ar(power)2 = 40
a(1+2(power)2) = 40
a(5) = 40
a= 40/5= 8
Fifth term (F5) = ar(power)4
= 8*2(power)4
=8*16
=128

Hund's rule of maximum multiplicity
describes the order in which electrons fill
subshells. It states that they will add into
degenerate(equal energy level) orbitals to
create the greatest multitude of orbitals
having an electron in them.

Q1 i The main difference between
thermoplastics and thermosets is that:
-Thermoplastics can be re-melted and
recycled fairly easily
-Thermosets typically are cured and
molded into shape and are not recycled
as easily
Q1 j.
Fermentation is a metabolic process that
converts sugar to acids, gases and/or
alcohol. It occurs in yeast and bacteria , but
also in oxygen-starved muscle cells, as in
the case of lactic acid fermentation .
Fermentation is also used more broadly to
refer to the bulk growth of microorganisms
on a growth medium. French microbiologist
Louis Pasteur is often remembered for his
insights into fermentation and its microbial
causes. The science of fermentation is
known as zymology.
