Answer:
Kc = 105062.5 at 298K
Explanation:
First of all, we state the equilibrium:
3O₂(g) ⇄ 2O₃(g)
We know data about equilibrium concentration of oxygen. We suppose 1 mol of oxygen at the begining. During the reaction, x moles have reacted.
As ratio is 2:3, we can determine how many moles of ozone have been produced.
(x . 2)/3
So we have the final concentration of oxygen, so, let's find out x
1 - x = 0.016 moles
x = 0.984 moles
Then, the [O₃] in equilibrium will be (0.984 . 2) /3 = 0.656.
We supose a volume of 1 L, so we have molar concentration to determine Kc. Let's state the expression for it:
Kc = [O₃]² / [O₂]³
Kc = 0.656² / 0.016³ → 105062.5
cu=1*63g=63g
n=2*14g=28g
o=6*16g=96g
total=187g/mol
122(1 mol/187)(6.02*10^23)= 3.92*10^23
Answer:
An exact number is a value that is known with complete certainty. Like for Examples of exact numbers are counted numbers of objects or certain unit conversions. For example, there are exactly 3 feet in 1 yard. There are exactly 12 eggs in a dozen. A class may contain exactly 25 students.
Explanation:
Hope this helps.

The lone pair of electrons in Caffeine are shown in RED color in attached figure.
Details:
In chemistry there are two types of electrons.
i) Bonding Pair Electrons:
These are those electrons which are being shared and are involved in making bonds. They are also called as sharing electrons. In given structure all the solid bonds either single or double are made up of bonding pair electrons.
ii) Lone Pair / Non-Bonding Pair Electrons:
Those electrons which doesn't take part in bonding and are not shared between atoms. In given structure the lone pair of electrons are found only on nitrogen atoms (single lone pair) and oxygen atoms (two lone pair of electrons) respectively.
