Answer:
The value of
of the an ethylamine is
.
Explanation:
The pH of the solution = 12.067
The pOH of the solution = 14 - pH =14-12.607 =1.933
![pOH=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D)
![1.933=-\log[OH^-]](https://tex.z-dn.net/?f=1.933%3D-%5Clog%5BOH%5E-%5D)
![[OH^-]=0.0117 M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D0.0117%20M)

Initially
0.342 M 0 0
At equilibrium
(0.342-x) x x
The value of x = ![[OH^-]=0.0117 M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D0.0117%20M)
The expression of
is given as:
![K_b=\frac{[C_2H_5NH_3^{+}][OH^-]}{[C_2H_5NH_2]}](https://tex.z-dn.net/?f=K_b%3D%5Cfrac%7B%5BC_2H_5NH_3%5E%7B%2B%7D%5D%5BOH%5E-%5D%7D%7B%5BC_2H_5NH_2%5D%7D)


The value of
of the an ethylamine is
.
An ionic bond is composed of a cation and anion, which are charged ions. You cannot have atoms with ionic bonds, because there is no opposite attraction between charges due to atoms having a net nuclear charge of zero. Therefore, a cation and anion would most likely be joined by an ionic bond.
Answer:
Anything that can be done to increase the frequency of those collisions and/or to give those collisions more energy will increase the rate of dissolving.
Explanation:
depended on the temperature
Answer: limiting reactant controls the amount of product formed in a chemical reaction.
