690 Kelvin is the boiling point of this compound.
Explanation:
Enthalpy is the sum of internal energy and the product of pressure and volume that is how much energy is in the substance.
Entropy is the measurement of randomness and measure of thermal energy per unit of temperature.
ΔH vap of compound is 46.55 kJ⋅ mol− or J.MOL-1
ΔS vap is 67.37 J⋅mol−1⋅K−1.
The boiling point or temperature can be calculated by the formula:
T= 
T =
= 690 Kelvin
The boiling point is the temperature when atmospheric temperature gets equal to
<u>Answer:</u>
Now it is given here that there are 325 tubes that are manufactured for sunscreen. And we also know that the percentage of sunscreen in benzyl salicylate is 2.5% here in one tube we have 2 Oz of sunscreen.
<u>Explanation:</u>
So sunscreen in 325 tubes will be 2 x 325= 650 Oz. Since we know the amount of sunscreen in 325 tubes the amount of Benzyl salicylate in all 325 tubes will be 650 x 0.025 = 16.25 Oz
<em>Now this can be converted into kg as 0.46 kg</em>.
Combustion is a chemical reaction in which a hydrocarbon reacts with oxygen to form carbon dioxide (CO2) and water (H2O). In other words, all the carbons get converted to CO2 while all the hydrogens get converted into H2O.
Incomplete combustion however, results in the formation of carbon monoxide (CO) and H2O.
Methane is a hydrocarbon with a molecular formula CH4. Thus complete combustion of methane can be expressed as-
CH4 + 2O2 → CO2 + 2H2O
