Liquid hexane reacts with gaseous oxygen gas to produce carbon dioxide and gaseous water. What is the theoretical yield of carbon dioxide formed by the reaction of 54.3g of hexane and 78.5g of oxygen?

C6H8 + 8O2 ===> 6CO2 + 4H2O ... balanced equation
moles hexane = 54.3 g x 1 mol/80 g = 0.679 moles
moles O2 = 78.5 g x 1 mol/32 g = 2.45 moles
Limiting reactant is Oxygen (O2) since need 8 x as much as C6H8
Theoretical yield of CO2 = 2.45 mole O2 x 6 mole CO2/8mole O2 = 1.84 moles CO2
1.84 moles CO2 x 44 g/mol = 80.9 g (answer to 3 sig figs)

Give two reactions which produce carbon dioxide in the lime kiln?
One reaction is calcium carbonate is calcium oxide plus carbon dioxide. Another reaction is carbon plus oxygen which equals carbon dioxide.

How does a candle produce carbon dioxide while it burns?
Any burning (oxidation reaction) produce carbon dioxide.
What happens in the reaction?
In the reaction of respiration glucose and oxygen are broken down to produce carbon dioxide and water

Does dark reaction of photosynthesis produce oxygen and ATP?
According to biologists, dark reaction in photosynthesis uses ATP in order to produce carbon dioxide. Once carbon dioxide is generated, then it can be used to synthesize glucose.

Sulfur burns in oxygen to produce sulfur dioxide type of reaction equals?
S + O2 à SO2 This is a combustion reaction
Is carbon dioxide a waste for a plant?
No, Carbon dioxide is used by the plant to produce sugars during photosysnthesis. In this reaction Oxygen is a waste or by-product
What does the preparatory reaction produce?
Oxygen gas is given off in the preparatory reaction of cellular respiration. It is the same as in photosynthesis in plants.
