Yes
Explanation:
Denatured ethanol fuel is a polar solvent, which is soluble in water. A
Polar solvent is a compound with a charge separation in chemical bonds, such as alcohol, most acids, or ammonia. These have affinity with water and will dissolve easily. Denatured fuel ethanol has a flash point of -5 ° F and a vapor density of 1.5, indicating that it is heavier than air.
Consequently, ethanol vapors do not rise, similar to the gasoline vapors they are looking for lower altitudes. The specific gravity of denatured fuel ethanol is 0.79, which indicates that it is lighter than water and has a self-ignition temperature of 709 ° F and a boiling point of 165-175 ° F. Like gasoline, the most denatured fuel, the greatest danger of ethanol as an engine fuel component is its flammability.
It has a wider flammable range than gasoline (LEL is 3% and UEL is 19%).
If a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced. Details about number of moles can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated as follows:
The following chemical equation was given as follows:
C3H8 + 502 = 3CO2 + 4H₂O
1 mole of C3H8 produced 3 moles of carbon dioxide
Hence, 3.53 moles of C3H8 will produce 3.53 × 3 = 10.59 moles of CO2.
Therefore, if a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced.
