The more acidic the substance is, the more the iron nails will corrode (this obviously depends on what your experiment is but hope this helped in some way)
Sorry i cant even read that
The pressure at the bottom : 19600 N/m²
<h3>Further explanation</h3>
Given
A ground water tank has its height 2m
Required
The pressure at its bottom
Solution
Hydrostatic pressure is the pressure caused by the weight of a liquid.
The weight of a liquid is affected by the force of gravity.
The hydrostatic pressure of a liquid can be formulated:
![\large{\boxed{\bold {P_h ~ = ~ \rho.g.h}}](https://tex.z-dn.net/?f=%5Clarge%7B%5Cboxed%7B%5Cbold%20%7BP_h%20~%20%3D%20~%20%5Crho.g.h%7D%7D)
Ph = hydrostatic pressure (N / m², Pa)
ρ = density of liquid (kg / m³)
g = acceleration due to gravity (m / s²)
h = height / depth of liquid surface (m)
ρ = density of water (kg / m³) = 1000
g = acceleration due to gravity = 9.8 m/ sec²
The pressure
![\tt P=1000\times 9.8\times 2=19600~N/m^2](https://tex.z-dn.net/?f=%5Ctt%20P%3D1000%5Ctimes%209.8%5Ctimes%202%3D19600~N%2Fm%5E2)
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
