I mostly believe in between D and B beacuse K3po4 and caco3 is not an element equation
Answer:
with the proton inside the nucleus
because it a essential for good heat transfer
Answer:
Final pH of the solution: 2.79.
Explanation:
What's in the solution after mixing?
,
where
is the concentration of the solute,
is the number of moles of the solute, and
is the volume of the solution.
.
Acetic (ethanoic) acid:
.
.
Hydrochloric acid HCl:
.
.
HCl is a strong acid. It will completely dissociate in water to produce H⁺. The H⁺ concentration in the solution before acetic acid dissociates shall also be
.
The Ka value of acetic acid is considerably small. Acetic acid is a weak acid and will dissociate only partially when dissolved. Construct a RICE table to predict the portion of acetic acid that will dissociate. Let the change in acetic acid concentration be
.
.
.
.
Rewrite as a quadratic equation and solve for
:

.
The pH of a solution depends on its H⁺ concentration.
At equilibrium
