Answer:
Mechanical Energy = A
Gravitational Energy = C
Nuclear Energy = B
Thermal Energy = D
Explanation:
Hope this helps you :) If any are wrong, I'm very sorry.
The idea of electric field was presented by Michael Faraday. The electrical field constrain acts between two charges, similarly that the gravitational field compel acts between two masses.
PH to maximize the dissociation of acetic acid so as to push back the amount of acetate dissociating from the mystery compound.
<span>
Ksp = [X+][C2H3O2-] = 9.5*10^-6 </span>
<span>Substituting in the desired value for [X+] </span>
<span>9.5*10^-6 = (5.0*10^-3)x </span>
x, or acetate concentration, is .0019
<span>Now, we calculate the Ka of acetic acid: </span>
<span>pKa = -logKa </span>
<span>4.76 = -logKa </span>
<span>Ka = 1.738*10^-5 </span>
<span>We want the concentration of acetate to be .0019, so we plug that into our acid dissociation constant expression: </span>
<span>Ka = [H+][C2H3O2-]/[HC2H3O2] </span>
1.738*10^-5<span> = [H+](.0019)/1</span>
<span>[H+] = .00915</span>
<span>pH = -log[H+] </span>
<span>pH = -log(.00915) </span>
pH = 2.04
