Answer:
Oxygen gas
Explanation:
Given expression:
CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O
Number of moles of oxygen gas = 1 mole
Number of moles of ethanol = 1 mole
Unknown:
The limiting reactant = ?
Solution:
The limiting reactant is the reactant in short supply in a chemical reaction. To find this specie, we always us the number of moles.
From the equation of the reaction:
1 mole of ethanol would require 3 moles of oxygen gas
But we have been given just 1 mole of oxygen gas instead of 3moles.
Therefore, oxygen gas is the limiting reactant.

Answer:
cycloocta-1,4-diene- isolated double bond
cycloocta-1,3-diene- conjugated double bond
cyclodeca-1,2-diene- cumulated double bond
cycloocta-1,3,5,7-tetraene- conjugated double bond
cyclohexa-1,3,5-triene (benzene) - conjugated double bond
penta-1,2,4-triene- cumulated and conjugated double bond
Explanation:
A conjugated double bond is a system that contains alternate double and single bonds. It is renowned for its unusual stability.
A cumulated double bond is a double bond system involving about three atoms e.g C=C=C.
An isolated double bond is a system of double bonds separated by more than one single bond.
