Answer: c. At equilibrium, the concentration of reactants is greater than the products
Explanation:
Equilibrium constant for a reaction is the ratio of concentration of products to the concentration of reactants each raised to the power its stoichiometric coefficients.
For the reaction:
Equilibrium constant is given as:
![K_{eq}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BN_2O_5%5D%7D%7B%5BNO_2%5D%5Ctimes%20%5BNO_3%5D%7D)
![2.1\times 10^{-20}=\frac{[N_2O_5]}{[NO_2]\times [NO_3]}](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B-20%7D%3D%5Cfrac%7B%5BN_2O_5%5D%7D%7B%5BNO_2%5D%5Ctimes%20%5BNO_3%5D%7D)
When
a) K > 1, the concentration of products is greater than the concentration of reactants
b) K < 1, the concentration of reactants is greater than the concentration of products
c) K= 1, the reaction is at equilibrium, the concentration of reactants is equal to the concentration of products
Thus as 
is 
which is less than 1,
the concentration of reactants is greater than the concentration of products

Oil makes it impossible for fur-bearing mammals to insulate<span>, this leaves them unprotected from the harsh elements out in the water. Birds and mammals will die from hypothermia without the ability to insulate from the freezing water.

Answer:
x means unknown it is an unknown value.
For example if you have 2 x you have 2 u know values.
Explanation:
If you want us to explain it further please provide a picture.
In 1905 Albert Einstein had proposed a solution to the problem of observations made on the behaviour of light having characteristics of both wave and particle theory. From work of Plank on emission of light from hot bodies, Einstein suggested that light is composed of tiny particles called <span>photons, </span>and each photon has energy.
Light theory branches in to the physics of <span>quantum mechanics, </span>which was conceptualised in the twentieth century. Quantum mechanics deals with behaviour of nature on the atomic scale or smaller.
As a result of quantum mechanics, this gave the proof of the dual nature of light and therefore not a contradiction.
