Question options: <em> a. have a crystal structure b. has an unpredictable chemical structure c. can be liquid or solid d. can be organic or inorganic .</em>

Answer:

options (a) and (c) applies

Explanation:

  • Minerals usually have a definite crystalline structure, however this is not always the case, as some naturally occurring minerals are not crystal like.
  • the chemical structure of minerals are predictable.
  • Minerals can only exist as solids. if any substance is in its liquid form then its not a mineral.
  • finally minerals can either be inorganic or organic.Inorganic minerals do not contain carbon, while organic minerals are made up of carbon

Minerals are solid, naturally occurring, inorganic compounds that possess an orderly internal structure and a regular chemical composition. Minerals should occur naturally. Hope this answers the question. Have a nice day. Feel free to ask more questions.

The only thing you need to put the followings into correct order is to remember that the smalles mass - the less volume it has. So, accordnig to this, the order should be like that : An ice crystal- A water molecule-An oxygen atom-The electron cloud-<span>An oxygen nucleus. Hope you will find it  helpful!</span>

Calculate the ph of a 0.60 m h2so3, solution that has the stepwise dissociation constants ka1 = 1.5 × 10-2 and 1.82 1.06 1.02 2.
Vsevolod [243]
Missing in your question Ka2 =6.3x10^-8
From this reaction:
 H2SO3 + H2O ↔ H3O+  + HSO3-
by using the ICE table :
                H2SO3     ↔    H3O     +    HSO3- 
intial         0.6                     0                  0
change     -X                      +X                +X
Equ         (0.6-X)                  X                   X

when Ka1 = [H3O+][HSO3-]/[H2SO3]
So by substitution:
1.5X10^-2 = (X*X) / (0.6-X) by solving this equation for X
∴ X = 0.088
∴[H2SO3] = 0.6 - 0.088 = 0.512
[HSO3-] = [H3O+] = 0.088

by using the ICE table 2:
                 HSO3-     ↔   H3O     +     SO3-
initial        0.088              0.088              0
change    -X                      +X                   +X
Equ         (0.088-X)          (0.088+X)          X

Ka2= [H3O+] [SO3-] / [HSO3-]
we can assume [HSO3-] =  0.088 as the value of Ka2 is very small
 6.3x10^-8 = (0.088+X)*X / 0.088
X^2 +0.088 X - 5.5x10^-9= 0 by solving this equation for X
∴X= 6.3x10^-8
∴[H3O+] = 0.088 + 6.3x10^-8
               = 0.088 m ( because X is so small)
∴PH= -㏒[H3O+]
       = -㏒ 0.088 = 1.06
