A net worth: $79.0 billion.
Value of stock : $3.20 billion.
New net worth:
$79.0 + $3.20 = $82.20 billion = $82.20 * 10^9 = $8.20 * 10^10

Calculate the equilibrium constant for the reaction using the balanced chemical equation and the concentrations of the substance

Oliga [24]

Answer:

4.75 is the equilibrium constant for the reaction.

Explanation:

$CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)$

Equilibrium concentration of reactants :

$[CO]=0.0590 M,[H_2O]=0.00600 M$

Equilibrium concentration of products:

$[CO_2]=0.0410 M,[H_2]=0.0410 M$

The expression of an equilibrium constant is given by :

$K_c=\frac{[CO_2][H_2]}{[CO][H_2O]}$

$K_c=\frac{0.0410 M\times 0.0410 M}{0.0590M\times 0.00600 M}$

$K_c=4.75$

4.75 is the equilibrium constant for the reaction.
