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:
The isotopic mass of 41K is 40.9574 amu
Explanation:
Step 1: Data given
The isotopes are:  
39K with an isotopic mass of 38.963707u and natural abundance of 93.2581%
40K with an isotopic mass of 39.963999u
41K wit natural abundance of 6.7302 %
Average atomic mass =39.098 amu  
Step 2: Calculate natural abundance of 40 K
100 % - 93.2581 % - 6.7302 %
100 % = 0.0117 % 
Step 3: Calculate isotopic mass of 41K
39.098 = 38.963707 * 0.932581 + 39.963999 * 0.000117 + X * 0.067302
39.098 = 36.33681 + 0.0046758 +  X * 2.067302
X = 40.9574 amu
The isotopic mass of 41K is 40.9574 amu

Answer:
 44° to 45°
Explanation:
The altitude of Polaris star  when viewed from New York City is somewhat between 44° to 45°. However, Polaris is directly overhead at the North Pole (90° of latitude); in other words, the angle between Polaris and the horizon at the North Pole is 90°. This angle is called "the altitude" of Polaris.
