For the reaction POCl3(g) ⇀↽ POCl(g) + Cl2(g) Kc = 0.30. An initial 0.3 moles of POCl3 are placed in a 3.1 L container with initial concentrations of POCl and Cl2 equal to zero. What is the final concentration of POCl3? 1. final concentration = 0.281774 M 2. final concentration = 0.077 M 3. final concentration = 0.185 M 4. final concentration = 0.039534 M 5. final concentration = 0.019767 M

The final concentration of is 0.019767 M

Explanation:

Molarity is calculated by using the equation:

Initial moles of = 0.3 moles

Volume of solution = 3.1 L

For the given chemical equation:

Initial:                0.097

At eqllm:         0.097-x             x              x

The expression of for above equation follows:

We are given:

Putting values in above expression, we get:

Neglecting the negative value of 'x' because concentration cannot be negative.

So, final concentration of = (0.097 - x) = (0.097 - 0.077233) = 0.019767 M

Hence, the final concentration of is 0.019767 M

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
