Answer:
B₂
Explanation:
The limiting reactant is always a reactant. You can determine which reactant is limiting by identifying which has the smaller mole-to-mole ratio with the product. This ratio can be found via the coefficients of the balanced reaction.
4 A₂ + 3 B₂ ---> 6 AB
4 moles A₂
------------------ = mole-to-mole ratio A₂/AB
6 moles AB
3 moles B₂
------------------ = mole-to-mole ratio B₂/AB
6 moles AB
Since the mole-to-mole ratio between B₂ and AB is smaller, B₂ must be the limiting reactant.

Hey there!
Oxygen needs two bonds to have a valence orbital of s²p⁶.
In a hexanal molecule, oxygen has a double bond with one carbon atom.
A double bond is when two pairs of electrons are being shared.
So your answer is b. 2.
Hope this helps!
The group number tells us about the size weight and molecule elements involved. Also tells us about what types it can form and combine with as well as its reactions also
