Answer:
This question is incomplete but the completed question is below
a) Identify the chemical equation that represents what would occur if naphthalene (C₁₀H₈) is burned in the presence of O₂
b) Identify how many moles of carbon dioxide would be released from the equation in (a) if 25.0 g of naphthalene were burned in the presence of excess oxygen.
c) Explain what would happen if only 1 mole of oxygen gas were available to interact with naphthalene in this reaction.
The answers to the questions are below
Step-by-step explanation:
a) The chemical reaction here will be a combustion reaction. A combustion reaction involves the burning of a substance (in this case an organic compound) in excess oxygen to produce carbon dioxide and water.
The balanced equation below shows what will happen when naphthalene (C₁₀H₈) is burned in the presence of O₂
C₁₀H₈ + 10O₂ ⇒ 10CO₂ + 4H₂O
b) The mass of naphthalene (C₁₀H₈) from the equation above is
when C= 12 and H = 1; C₁₀H₈ = (10 × 12) + (1 × 8) = 128 g
Mass of C₁₀H₈ from the equation in (a) above is 128 g
If 128g of C₁₀H₈ ⇒ 10 moles of CO₂
25g of C₁₀H₈ ⇒ X moles of CO₂
where X is the unknown
X = 25 × 10/128
X = 1.95 moles of CO₂
1.95 moles of CO₂ would be released from the equation in (a) if 25.0 g of naphthalene were burned in the presence of excess oxygen
(c) If just 1 mole of oxygen gas was available for the reaction in (a) above, the reaction would have been an incomplete combustion. An incomplete combustion is the process in which a substance burns in insufficient oxygen to produce carbon monoxide (CO) and water.
