Answer:
4 moles CO₂ = 4 moles O₂
Explanation:
The incorrect mole ratio is 4 moles CO₂ = 4 moles O₂.
Let us write the reaction equation:
2C₂H₅OH + 7O₂ → 4CO₂ + 6H₂O
To write mole ratios in a chemical reaction, we must ensure the equation is balanced.
Since the given expression is balanced,
Then 4 moles CO₂ = 4 moles O₂ is not correct;
Rather;
4 moles CO₂ = 7 moles O₂ is the right expression

Chemical Reactions and Moles of Reactants and Products
That is, it requires 2 moles of magnesium and 1 mole of oxygen to produce 2 moles of magnesium oxide. If only 1 mole of magnesium was present, it would require 1 ÷ 2 = ½ mole of oxygen gas to produce 2 ÷ 2 = 1 mole magnesium oxide.
The salt causes the water to freeze at a lower temperature. When a solute, aka salt, is introduced to the system, the freezing point is lowered. This makes the water freeze at a lower temperature.
