Answer:- 
Solution:- percent ionization = 
where, 
is the equilibrium concentration of product ion and c is the initial concentration of the acid.
Let's plug in the values in the formula:
In general, the acid is represented as HA, the ice table is shown as:
I 0.10 0 0
C -X +X +X
E (0.10 - X) X X
where X is the change in concentration that we already have find out using percentage ionization formula.
![Ka=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
Let's plug in the values in it:
0.003 is almost negligible as compared to 0.10, so (0.10 - 0.003) could be taken as 0.10.
Second choice is the right one.
First find the volume of the cubic lattice given edge
length of 646 pm or 6.46x10^-8 cm.
volume = (6.46x10^-8 cm)^3
volume = 2.7x10^-22 cm^3
The total mass of the lattice is:
mass = (5.850 g/cm^3) * 2.7x10^-22 cm^3
mass = 1.577x10^-21 grams
The molar mass of tin is 118.71 g/mol and the Avogadros
number is 6.022 x 10^23 atoms/mol, hence:
Sn atoms = [1.577x10^-21 g / (118.71 g/mol)] * 6.022 x
10^23 atoms/mol
Sn atoms = 8 atoms
Can you tell question nicely i didn’t understand the question
Answer:
In context|chemistry|lang=en terms the difference between halogen and halide. is that halogen is (chemistry) any element of group 7, ie fluorine, chlorine, bromine, iodine and astatine, which form a salt by direct union with a metal while halide is (chemistry) a salt of any halogen acid.
