What is the heat of combustion of naphthalene?
-5133 kJ mol-1
The heat of combustion of naphthalene (C10H8(s)) at constant volume was measured to be -5133 kJ mol-1 at 298 K.
What is the enthalpy of fusion for naphthalene?
19.0 KJ mol
Given that the latent heat of fusion of naphthalene is `19.0 KJ mol^(-1)` and its melting point is `80.2^(@)C`.
How do you calculate the heat of combustion of naphthalene?
Problem: The standard enthalpy of combustion of naphthalene is -5157 kJ/mol. Calculate its standard enthalpy of formation. The reaction for the combustion of naphthalene is:C10H8 (s) + 12 O2 (g) → 10CO2 (g) + 4 H2O (l)
What is the formula of naphthalene?
C10H8
Naphthalene/Formula
What is the heat of combustion of benzoic acid?
26438 f 4 j/g
The mean value of the absolute heat of combustion of benzoic acid under standard bomb conditions in some series of determinations carried out in the years 1946-1948 is 26438 f 4 j/g.
Is naphthalene acidic or basic?
The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different pKa. The pKa’s of benzoic acid and 2-naphthol are 4.17 and 9.5, respectively, while naphthalene is a neutral compound.
What is the chemical formula of benzoic acid?
C7H6O2
Benzoic acid/Formula
Does heat of combustion change with temperature?
Heats of combustion are usually determined by burning a known amount of the material in a bomb calorimeter with an excess of oxygen. By measuring the temperature change, the heat of combustion can be determined.
What is the specific heat capacity of naphthalene?

What was the name of the 1930 study on naphthalene?
The heat capacities, entropies and free energies of twelve aromatic hydrocarbons , J. Am. Chem. Soc., 1930, 52, 1547-1558. [ all data ] David, D.J. , Determination of specific heat and heat of fusion by differential thermal analysis.
What is the role of naphthalene in essential oils?
Naphthalene is an aromatic hydrocarbon comprising two fused benzene rings. It occurs in the essential oils of numerous plant species e.g. magnolia. It has a role as a volatile oil component, a plant metabolite, an environmental contaminant, a carcinogenic agent, a mouse metabolite and an apoptosis inhibitor.
What are the different names for naphthalene tar?
Other names: Albocarbon; Dezodorator; Moth flakes; Naphthalin; Naphthaline; Naphthene; Tar camphor; White tar; Camphor tar; Moth balls; Naftalen; NCI-C52904; Mighty 150; Mighty RD1; Rcra waste number U165; UN 1334; UN 2304; NSC 37565 Permanent link for this species.
