Answer:
The <u>equilibrium constant</u> is:
Explanation:
The correct equation is:
Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.
The equation for the equilibrium constant is:
Substituting:
Answer:
The pH of the solution increases.
Explanation:
Acetic acid is a weak acid, this means it does not dissociate completely in aqueous solution.
Sodium acetate on the other hand is a salt which dissociates to give acetate ions ad sodium ion.
Also, sodium acetate is the conjugate base of acetic acid. A mixture of a weak acid and its conjugate base is a buffer solution.
The mixture leads to a greater concentration of acetate ion, CH3COO-. shere is an increase in the pH of the solution.
So, when you are adding sodium acetate to a solution of acetic acid, concentration of acetate anions increases. Thus, there will be a decrease of hydronium ions resulting in pH increase.
I´m pretty sure its magnesium iron silicate.
Answer:
Dalton's atomic theory has been modified as
Explanation:
Atoms of same element may not have same atomic mass. For example, some atoms of chlorine have atomic mass 35 amu while others have atomic mass 37 amu. Such atoms of same element having different atomic masses are called isotopes
Nuclear reactions happen inside the nucleus,so it changes the protons and neutrons
