Explanation:
Chemical reaction equation for the give decomposition of 
is as follows:.
And, initially only is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,
= 0.23 aatm
So, = 2.3 - 2(0.23)
= 1.84 atm
Now, expression for 
will be as follows.
= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is 
.
Answer:
are gases at room temperature
usually do not react with other elements
are in a group called the noble gases
are nonmetals
Explanation:
The elements in group 18 or group O are the inert elements. They have completely outermost shell and are not reactive. Every atom reacts with another in order to be like the noble gases.
- All of the elements here are gaseous.
- They do not readily react with other elements.
- They are called noble gases, inert gases, or group O elements.
It should be noted that group 17 elements are very reactive compared to the group O elements.
Hello sir
is anyone thing wrong without u ?
anything that u r feeling alone?
u can share with me is u want
