Naphthalene is a white crystalline solid with a characteristic odor. It is soluble in organic solvents but insoluble in water. Naphthalene is produced commercially from coal tar and is used in the manufacture of plastics, …

At 20 0C, naphthalene is a solid with low volatility. Characterized by its low solubility, it will moderately volatilize once dissolved and adsorbs strongly to organic matter. When present in soil, this compound will undergo light volatilization and solubilize slowly.

Abstract. Both the recent classification of naphthalene as a possible human carcinogen and its ubiquitous presence motivate this critical review of naphthalene's sources and exposures. We evaluate the environmental literature on naphthalene published since 1990, drawing on nearly 150 studies that report emissions and …

Question: 2.9b. Mass transfer from a flat plate A 1-m square thin plate of solid naphthalene is oriented parallel to a stream of air flowing at 20 m/s. The air is at 330 K and 101.3kPa. The naphthalene remains at 290 K; at this temperature the vapor pressure of naphthalene is 26 Pa. Estimate the moles of naphthalene lost from the plate per hour, …

A 1m square, thin plate of solid naphthalene is oriented parallel to a stream of air flowing at 20 m/s. The air system is at 27 degree C, with kinematic viscosity of 1.57 Times 10^-5 m^2 s^-1.

Enthalpy of combustion of solid at standard conditions (nominally 298.15 K, 1 atm.)

This study convincingly demonstrates a unique example of the self-assembly of a naphthalene diimide (NDI)-appended peptide into a fluorescent J-aggregate in aqueous media. Moreover, this aggregated species shows a remarkable yellow fluorescence in solid state, an unusual phenomenon for NDI-based compounds. The …

Sublimation: Examples, Application, Phase Diagram. When a substance changes directly from its solid state to its gaseous state, this transition is known as sublimation in the chemical sciences. Crystalline iodine and solidified carbon dioxide are chemicals that sublimate at standard ambient temperatures and atmospheric pressure.

Naphthalene, a polycyclic aromatic hydrocarbon (PAH), is a compound with a unique set of physical and chemical properties that govern its solubility in various solvents, particularly water. Understanding the solubility of naphthalene is crucial in fields ranging from environmental remediation to industrial applications. This comprehensive …

However, the high octanol–water partition coefficient of phenanthrene and naphthalene leads to hydrophobicity, and the compounds are easily assigned to the …

The vapor pressure of solid naphthalene at 23 degree C is 0.07 mmHg. A naphthalene sphere of diameter 1 cm is suspended in still air. How long is required for the sphere to lose 50% of its initial mass? To answer this …

Naphthalene is a white crystalline solid with a characteristic odor that is detectable at low concentrations. It is insoluble in water, but soluble in other organic solvents, especially closer to their boiling point.

The data generated by static and dynamic laboratory testing sup- ported by field performance demonstrated that NA-LUBE KR al- kylated naphthalene formulated into a …

A 1.75-cm diameter naphthalene mothball is suspended in an air stream at 280 K, 1.0 atm, and constant velocity of 1.4 m/s. Solid naphthalene exerts a vapor pressure of 2.8 Pa at 280 K. Consequently, the naphthalene very slowly sublimes into the passing air stream, with the rate limited by convective mass transfer.

Here's the best way to solve it. A sample of solid naphthalene is introduced into an evacuated flask and allowed to sublime. Use the data below to calculate the equilibrium vapor pressure of naphthalene (C10H8) in the flask at 35∘C.
