Atmospheric
pressure<span>, sometimes also called barometric pressure, is the pressure exerted by the weight of air in
the </span>atmosphere of Earth<span> (or that of another planet)</span>
1 atm is equivalent to = 101325
Pa
= 760 mmHg
= 760 torr
= 1.01325 bar
So 1.23 atm is equal to
= 124629.8 Pa
= 934.8 mmHg
= 934.8 torr
<span>= 1.2462 bar</span>

A lone pair is a pair of valence electrons that are not shared with another atom and is sometimes called a non-bonding pair.
Composting is not a technological way of improving air quality.

Answer:
The concentration of [A⁻] is 0,0166M
Explanation:
In the equilibrium of a weak acid:
HA ⇄ A⁻ + H⁺
The solution of a weak acid contains, initially, the concentration of HA is Y. In equilibrium, the concentrations of each compound are:
[HA] = Y-x
[A⁻] = x
[H⁺] = x
That means [H⁺] = [A⁻].
The pH is defined as -log₁₀ [H⁺]. As the pH was 1,78:
1,78 = -log₁₀ [H⁺]
0,0166M = [H⁺]
As [H⁺] = [A⁻], <em>the concentration of [A⁻] is 0,0166M</em>
<em></em>
