At a certain temperature, 0.900 mol of SO3 is placed in a 2.00-L container.

2SO3(g)<--> 2SO2(g)+O2(g)

At equilibrium, 0.130 mol of O2 is present. Calculate Kc.

Kc = 2.34 mol*L

Explanation:

The calculation of the Kc of a reaction is performed using the values of the concentrations of the participants in the equilibrium.

A + B ⇄ C + D

Kc = [C] * [D] / [A] * [B]

According to the reaction

Kc = [SO2]^2 * [O2]^2 / [SO3]^2

Knowing the 0.900 mol of SO3 is placed in a 2.00-L it means we have a 0.450 mol/L of SO3

0.450 --> 0 + 0 (Beginning of the reaction)

0.260 --> 0.260 + 0.130 (During the reaction)

0.190 --> 0.260 + 0.130 (Equilibrium of the reaction)

Kc = [0.260]^2 + [0.130]^2 / [0.190]^2

Kc = 2.34 mol*L

Explanation:

In general, biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.Examples of biotic factors include:

Grass as producers (autotrophs).

Mouse, deer, and owl as consumers (heterotrophs).

And earthworms as decomposers (detritivores).

To further understand the term "biotic factors", it's helpful to look at the meaning of the terms "biotic" and "abiotic."

Biotic means pertains to life. (Remember that Biology is the study of life?) Abiotic means pertaining to no life.

Abiotic examples include things that are not alive but you will find in an ecosystem such as air, gases, water, sand, stones and rocks.
