The initial concentration of acid ha in solution is 0.39 m. if the ph of the solution at equilibrium is 0.76, what is the percen
Alexus [3.1K]

The percent ionization of the acid is 44.56%

<h3>How can we calculate the percent ionization of the acid?</h3>

To calculate the percent ionization of the acid we are using the formula,

The H⁺ ion concentration [H⁺] = C x,

where, we are given,

C= concentration of the acid.

=0.39 M

x= degree of dissociation of the acid.

And one more thing we are given that, the pH of the acid=0.76.

So from the above statement we can say that,

pH = - log [H⁺]

Or,0.76 = -log [H⁺]

Or, log [H⁺] = -0.76

Or, [H⁺] = antilog -0.76

Or,[H⁺]= 10^-0.76

Or,[H⁺]=0.1738.

Now from the above calculation we know, the H⁺ ion concentration= 0.1738 M.

Now we put the known values in the above equation,

[H+]= Cx

Or,0.1739= 0.39 x

Or, x= 0.4459

From the above calculation we can conclude that the percent Ionization of the acid= 0.4459 X 100= 44.59%≈45%

Orlov [11]
<h2>Answer:</h2>

<em><u>The energy of a system always remains constant as it can be converted from one type two another type. It can never be lost or created.</u></em>

<h3>Explanation:</h3>

Lets take an example of the boy riding a bicycle.

The boy is using the biochemical energy in his body to run the pedals up and down in a cycle form.

The biochemical energy is converted into the potential energy in the pedal.

As the pedal moves, it gives energy to move the wheels of the cycle and consequently the cycle will move forward.

Hence the potential energy is converted into the kinetic energy.

If the road is not clear, a lot of energy is needed to move the wheels or cycle as compared to clear road. Because some of the energy will be converted into heat during friction.

bogdanovich [222]

Answer:

The Reasons for which petroleum is the chosen fuel for transportation in the U.S. include number 1) and 2).

Explanation:

The main reasons why oil is the most used fuel in the USA is because of its energy potential with a high combustion power and a better octane rating compared to other fuels. Thus, fossil fuel derived from oil has a high energy value per unit volume and an ability to quickly start or stop providing energy.
