<u>Answer:</u> The concentration of hydrogen ions is 
<u>Explanation:</u>
We are given:
Concentration of acid = 0.22 M
The chemical equation for the dissociation of monoprotic weak acid follows:
<u>Initial:</u> 0.22
<u>At eqllm:</u> 0.22-x x x
The expression of 
for the above equation follows:
![K_a=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
We are given:
Putting values in above equation, we get:
Neglecting the negative value of 'x', because concentration cannot be negative
So, equilibrium concentration of hydrogen ions = x = 0.00047 M =
Hence, the concentration of hydrogen ions is
A FAULT is a fracture or break in Earth's surface
Answer:
The wavelength of radiation = 8.2 x 10⁻⁵
Explanation:
by the formula
v x λ = C
v = frequency
λ = wavelength
C = speed of light (3 x 10⁸ m/s)
λ = C / v
λ = 3 x 10⁸ / 3.68 x 
λ = 8.2 x 10⁻⁵
Answer:
proton
Explanation:
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
Hi there,
NH3 has the weight of 17.03 grams, and SF6 has the weight of 146.06 grams
so in total, there is 163.09 grams
Hope this helps :P
