Combustion equation of n-hexane:
2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
a)
Assuming we have 100 moles of air,
Oxygen = 20.9 moles
n-hexane required = 20.9/19 x 2
= 2.2 moles
LFL = Half of stoichometric amount = 2.2 / 2 = 1.1
LFL n-hexane = 1.1%
b)
1.1 volume percent required for LFL
1.1% x 1
= 0.0011 m³ of n-hexane required
KE=3070.625 J
Height = 3.686 m

mass of bike+rider=85 kg
velocity = 8.5 m/s
Conservation of energy :
(KE+PE)₁ (downhill) = (KE+PE)₂ (up the hill)
PE₁=0⇒h=0
KE₂=0⇒v=0(stop), so equation becomes :
KE₁=PE₂
<u>Answer:</u>
The very early discovery of particles that were subatomic was proposed by Dalton, which was then negated by the postulates suggested by Thomson that proved Dalton's theory.
<u>Explanation:</u>
The structural arrangement of atoms were approved by Thomson and Rutherford using the technique of air condition in x-ray showing the arrangement of protons and neutrons within Centre.
A nucleus and the negative particles that we called electrons moving around which were also shown to be much lighter than the particles present in the centre.
