Amixture initially contains a, b, and c in the following concentrations: [a] = 0.350 m , [b] = 0.650 m , and [c] = 0.300 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.220 m and [c] = 0.430 m . calculate the value of the equilibrium constant, kc.

The value of equilibrium constant, for the given reaction is 12.85.

Explanation:

For the given chemical equation:

At t = 0      0.350M     0.650M      0.300M

At  (0.350 - x)    (0.650 - 2x)     (0.300 + x)

We are given:

Equilibrium concentration of A = 0.220 M

Forming an equation for concentration of A at equilibrium:

Thus, the concentration of B at equilibrium becomes =

Equilibrium concentration of C = 0.430 M

The expression of for the given chemical equation is:

Putting values in above equation:

Hence, the value of equilibrium constant, for the given reaction is 12.85.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
