1.4 moles of propane react with 16 moles of oxygen gas in a combustion reaction, how many moles of carbon dioxide is formed which is the limiting reagent?

Answer is: 9.6 moles of carbon dioxide is formed and oxygen is limiting reagent.

Balanced chemical reaction: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
n(C₃H₈) = 4 mol; a
n(O₂) = 16 mol; limiting reagent.
From balanced chemical reaction: n(C₃H₈) : n(O₂) = 1 : 5.
For 4 moles of propane, 20 moles of oxygen is needed.
n(O₂) : n(CO₂) = 5 : 3.
n(CO₂) = 3 · 16 mol ÷ 5.
n(CO₂) = 9.6 mol.

It's either 3 or that ,,but if not than choose 4

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
