<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:
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

Hydrogen chloride and oxygen react to form water and chlorine, like this:
Use this chemical equation to answer the questions in the table below.
Suppose 155. mmol of HCl and 38.8 mmol of O₂ are added to an empty flask. How much HCl will be in the flask at equilibrium?
(1) None.
(2) Some, but less than 155. mmol,
(3) 155. mmol,
(4) More than 155. mmol,
Answer : The correct option is, (1) None
Explanation :
The given balanced chemical reaction is:
From the balanced chemical reaction, we conclude that
As, 4 mmole of HCl react with 1 mmoles of
So, 155. mmole of HCl react with mmoles of
That means, is excess reagent and
is a limiting reagent. All the moles of HCl will consume.
Hence, the correct option is, None.
