Isotope is two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei.

Carbon would have 6 protons, 6 Neutrons and 6 electrons.

Sulfur would have 16 protons, 16 neutrons and 16 electrons.

I hope that was a little helpful!

Exactly 1.0 mol N2O4 is placed in an empty 1.0-L container and is allowed to reach equilibrium described by the equation N2O4(g)

lora16 [44]

Answer: The value of equilibrium constant is 0.997

Explanation:

We are given:

Percent degree of dissociation = 39 %

Degree of dissociation, $\alpha$ = 0.39

Concentration of $N_2O_4$ , c = $\frac{1mol}{1L}=1M$

The given chemical equation follows:

$N_2O_4\rightleftharpoons 2NO_2$

Initial: c -

At Eqllm: $c-c\alpha$ $2c\alpha$

So, equilibrium concentration of $N_2O_4=c-c\alpha =[1-(1\times 0.39)]=0.61M$

Equilibrium concentration of $NO_2=2c\alpha =[2\times 1\times 0.39]=0.78M$

The expression of $K_{c}$ for above equation follows:

$K_{c}=\frac{[NO_2]^2}{[N_2O_4]}$

Putting values in above equation, we get:

$K_{c}=\frac{(0.78)^2}{0.61}\\\\K_{c}=0.997$

Hence, the value of equilibrium constant is 0.997
