How do you calculate the heat of formation of naphthalene?

1. 14.4 kcal. B.
2. 17.4 kcal. C.
3. 16.4 kcal. D.
4. 15.4 kcal. Medium. Solution. Verified by Toppr. B.
5. 17.4 kcal. Standard heat of formation of C10​H8​ = 10×heat of formation of CO2​ + 4× heat of formation of water – heat of combustion of naphthalene. Heat of formation of C10​H8​ = 10∗(−94)+(−68. 4)−(1231) = 17. 4kcal.

What is the delta H of naphthalene?

The standard enthalpies of formation ΔH°f[naphthalene TCNQ(c), 298.15 K]=716.95±7.30 kJ/mol, ΔH°f [anthracene TCNQ(c), 298.15 K] =763.84±4.87 kJ/mol, and ΔH0f[TMPD(c), 298.15 K]=39.60±3.85 kJ/mol were measured by oxygen combustion calorimetry.

### Is naphthalene poisonous to humans?

Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage. EPA has classified naphthalene as a Group C, possible human carcinogen.

### Is camphor and naphthalene same?

As nouns the difference between camphor and naphthalene is that camphor is (organic compound) a white transparent waxy crystalline isoprenoid ketone, with a strong pungent odour, used in pharmacy while naphthalene is a white crystalline hydrocarbon manufactured from coal tar; used in mothballs.

What is the formula of naphthalene?

C10H8
Naphthalene/Formula

What is the freezing point of naphthalene?

80.26 °C
Naphthalene/Melting point

## Is naphthalene a liquid?

Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible.

## How does naphthalene cause death in humans?

It is converted to 1-naphthol and 2-naphthol, which can be excreted though the kidney. When naphthalene is metabolized in the liver, oxidative stress induces massive hemolysis, resulting in hemolytic anemia, methemoglobinemia, hemoglobinuria, and jaundice.

What will happen if I eat naphthalene?

Naphthalene is a white solid substance with a strong smell. Poisoning from naphthalene destroys or changes red blood cells so they cannot carry oxygen. This can cause organ damage.

Is camphor good for skin?

Camphor for skin Lotions and creams containing camphor can be used to relieve skin irritation and itchiness and may help to improve the overall appearance of skin. It has antibacterial and antifungal properties that make it useful in healing infections.

### How to calculate the heat of combustion of naphthalene?

Heat of combustion= 122.12 g mol−1 This gives -3228 kJ mol-1 /(4.184 kJ kcal-1 /122.12 g = 6.318 kcal/g The factor for the 1341 calorimeter with an 1108 Oxygen Combustion Vessel will usually fall within a range from 2410 to 2430 calories per degree Celsius, with the exact value for each installation to be determined by the user.
