Answer:
The molecules of oxygen should be placed as reactants in the equation.
Explanation:
1: N₂ + O₂ → 2NO
2: 2NO + O₂ → 2NO₂
complete reaction:
N₂ + 2O₂ → 2NO₂
- In both intermediate equations' oxygen is used as reactant because the end product is the product of the combination of nitrogen and oxygen. So in the complete or overall reaction, oxygen should also be placed as reactant.
We can not place oxygen at the side of products neither we can cancel it because, products can only be obtained at the end of the reaction but according to the equations' oxygen is not the end product of the reaction. But the addition into the reaction (Eq. 2) to make the new product.
Also, we can not cancel it because to cancel out molecules of oxygen should be present at the both sides with same amount in the stoichiometric equation.
Hence, in a balanced chemical equation, oxygen should be written as a reactant by using the correct number of moles.

Answer:
Explanation:
The blow-by gases that escape past the piston rings and get into the crankcase are mostly unburned fuel-air mixture.
The fuel is largely a mixture of hydrocarbons (HCs)
.
The PCV system captures these gases and feeds them back to the cylinder for further combustion.
A. is wrong. Carbon dioxide exits through the exhaust.
C. is wrong. Most of the oxygen in the incoming air is used for combustion in the cylinders.
D is wrong. The NOx gases exit via the exhaust and are trapped by the catalytic converter.
