It's not an element or a compound because it's not pure or something like oxygen... it is a homogeneous mixture like tea and sugar
Answer:
Amide
Explanation:
O=NH2 is the Amide group versus NH2, which is the amine group.
According to the reaction equation:
Hf(aq) + H2O (l)↔ H3O+ (aq) + F(aq)
initial 1 m 0 0
-X +X +X
(1-x) X X
We assumed that [H3O+] = X
so. at eqilibrium:
Kc = [H3O] [ F] / [Hf] when we have Kc so by substitution:
3.5x10^-4 = X^2 / (1-X)
∴X^2 = 3.5x10^-4 - 3.5x10^-4 X
X^2 + 3.5x10^-4 X - 3.5x10^-4= Zero
by solving this equation:
(X-1.9x10^-2)(X + 1.9x10^-2) = Zero
∴X = 1.9x10^-2
∴ the equilibrium constatnt of H3O = 1.9x10^-2 M
Answer:
When an acid and a base are placed together, they react to neautralise the acid and base properties, thus making a salt.
Explanation:
The compound formed by the caption of the base and the anion of the acid is called a salt.
