Answer:
Explanation:
From the given information:
The equation for the reaction can be represented as:

The I.C.E table can be represented as:
                      2SO₂              O₂                   2SO₃
Initial:             14                  2.6                     0
Change:        -2x                -x                      +2x
Equilibrium:   14 - 2x          2.6 - x                2x 
However, Since the amount of sulfur trioxide gas to be 1.6 mol.
SO₃ = 2x, 
then x = 1.6/2
x = 0.8 mol
For 2SO₂; we have 14 - 2x 
= 14 - 2(0.8)
= 14 - 1.6
= 12.4 mol
For O₂; we have 2.6 - x
= 2.6 - 1.6
= 1.0 mol
Thus; 
[SO₂] = moles / volume = ( 12.4/50) = 0.248 M ,
[O₂] = 1/50 = 0.02 M ,  
[SO₃] = 1.6/50 = 0.032 M
Kc = [SO₃]² / [SO₂]² [O₂]
= ( 0.032²) / ( 0.248² x 0.02)
= 0.8325
Recall that; the equilibrium constant for the reaction  = 0.8325;
 = 0.8325;
If we want to find: 

Then:


Since no temperature is given to use in the question, it will be impossible to find the final temperature of the mixture. 
 
        
             
        
        
        
Answer:
D.) They often form hydroxide ions.
Explanation:
They generate hydroxide ions in water. they are soapy to touch and bitter in taste. they conduct electricity.
(all bases have hydroxide ions)
