Answer:
Kc = 50.5
Explanation:
We determine the reaction:
H₂  +  I₂   ⇄   2HI
Initially we have 0.001 molesof H₂
and 0.002 moles of I₂
If we have produced 0.00187 moles of HI in the equilibrium we have to know, how many moles of I₂ and H₂, have reacted.
            H₂     +      I₂      ⇄   2HI
In:     0.001       0.002           -
R:       x                 x                2x
Eq:  0.001-x    0.002-x      0.00187  
x = 0.00187/2 = 9.35×10⁻⁴ moles that have reacted
So in the equilibrium we have:
0.001 - 9.35×10⁻⁴ = 6.5×10⁻⁵  moles of H₂
0.002 - 9.35×10⁻⁴ = 1.065×10⁻³ moles of I₂
Expression for Kc is =  (HI)² / (H₂) . (I₂)
0.00187 ² /  6.5×10⁻⁵ . 1.065×10⁻³ = 50.5
 
        
             
        
        
        
Answer:
Option D. 5.5
Explanation:
The equation is this:
2A + 6B  ⇒  3C
With the amounts that we were given, let's determine which is the <em>limting reactant</em>
2 A reacts with 6 B
4 A will react with ( 4 .6)/2 = 12B
I have 11 B, so the limiting is B
6 B react with 2 A
11 B will react with (11 .2 )/6 =3.66 A
I have 4 A, so A is the excess.
6 B produce 3 C
11 B will produce ( 11 .3)/6 = 5.5C
 
        
             
        
        
        
The answer is P 
You can count how many electrons in the picture 
Or you can search for the one who has 3 electrons in the outer shell
