Find the equilibrium concentrations of a, b, and c for a=1, b=1, and c=2. assume that the initial concentrations of a and b are each 1.0 m and that no product is present at the beginning of the reaction.

consider the following reaction and associated equilibrium constant:
aa(g)+bb(g)⇌cc(g), kc = 4.0

The equation for Kc:
Kc = [C]² / [A] [B]

Let the equilibrium concentration of C be x
Then,
the equilibrium concentration of A = 1-x
the equilibrium concentration of B = 1-x

The equation becomes:
4 = x² / (1 - x)²
3x² - 8x + 4 = 0
x = 2, x = 2/3
The first answer is not possible so x = 2/3
[A] = 1 - 2/3 = 1/3
[B] = 1 - 2/3 = 1/3

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
