D. Should be correct- the other ones don’t make sense
Answer is: <span>the percent ionization is 0,19%.
</span>Chemical reaction: HA(aq) ⇄ H⁺(aq) + A⁻(aq).
Ka(HA) = 3,6·10⁻⁷.
c(HA) = 0,1 M.
[H⁺] = [A⁻] = x; equilibrium concentration.
[HA] = 0,1 M - x.
Ka = [H⁺] · [A⁻] / [HA].
0,00000036 = x² / 0,1 M - x.
Solve quadratic equation: x = 0,00019 M.
α = 0,00019 M ÷ 0,1 M · 100% = 0,19%.
First we calculate the concentration of HCl:
Moles = mass / Mr
= 25 / 36.5
= 0.685 mol
Concentration = 0.685/1.5 = 0.457 mol / dm³
For a strong monoprotic acid, the concentration of hydrogen ions is equal to the acid concentration.
pH = -log[H+]
pH = -log(0.457)
= 0.34
There was an increase in kinetic energy during the segment C and in other segments
Recall: That temperature is a measure of the average kinetic energy, so increasing temperature all cause increasing kinetic energy and vice versa.
However too, the heat energy which is added during the phase change is usually used to overcome forces in order to hold the molecules together.
<h3>What is kinetic energy?</h3>
Kinetic energy is the type of energy an object or a body posesss due to it motion
The body usually maintains it's kinetic energy unless the speed changes
<h3>What it potential energy?</h3>
Potential energy is a type of energy an object or a body had due to its relative position.
