The common way electrons are found in shells or orbitals that surround the nucleus of an atom.I hope it helped
Answer:
The balanced chemical equation will be "
".
Explanation:
The given equation is:
![2NO_{2}\rightarrow 2NO+O_{2}](https://tex.z-dn.net/?f=2NO_%7B2%7D%5Crightarrow%202NO%2BO_%7B2%7D)
<u>Step 1:</u>
<u></u>
...(equation 1)
<u>Step 2:</u>
<u></u>
...(equation 2)
On adding "equation 1" and "equation 2", we get
⇒ ![NO_{2}+NO_{2}+O\rightarrow NO+O+NO+O_{2}](https://tex.z-dn.net/?f=NO_%7B2%7D%2BNO_%7B2%7D%2BO%5Crightarrow%20NO%2BO%2BNO%2BO_%7B2%7D)
⇒ ![2NO_{2}\rightarrow 2NO+O_{2}](https://tex.z-dn.net/?f=2NO_%7B2%7D%5Crightarrow%202NO%2BO_%7B2%7D)
The second step:
⇒ ![NO_{2}+O\rightarrow NO+O_{2}](https://tex.z-dn.net/?f=NO_%7B2%7D%2BO%5Crightarrow%20NO%2BO_%7B2%7D)
Hot air rising and cooler air falling.
