Explain what would happen if only 1 mole of oxygen gas were available to interact with naphthalene in this reaction.

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

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.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
