Answer:
Coefficient in front of the 
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side, 
must be multiplied by 6 and by 4
Left side, 
is multiplied by 5 and 
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the in the balanced equation - 4</u>
The compound that ontains the most deactivated aromatic ring is the one called Nitrogen dioxide also knwon as NO2. Let me explain a little bit more about the aromatic rings. These rings are simple aromatics, or arenes, that consist of a conjugated planar ring system. Nitrogen generally is a simple aromatic ring that can be heterocyclic because containsnon-carbon ring atoms. The rings of the nitrogen can be separated into basic aromatic rings and that is why this ompound is also refered as a deactivated aromatic ring.
3. A full octet (8 electrons) is needed to be stable. So if the atom gets 3 more atoms it will be stable.
Answer:
homogeneous mixture must be the answer
Answer:
Kc = 0.042
Explanation:
PCl₅ → PCl₃ + Cl₂
The equilibrium constant's equation will be
Kc = [PCl₃] [Cl₂] / [PCl₅]
Kc = (0.02 x 0.02) / 0.0095
Kc = 0.0421
The equilibrium constant for the given reaction is 0.0421.
