Propane is commonly used to heat gas grills. Using the balanced equation below and stoichiometry, which of the following is FALSE? C3H8 + 5O2 → 3CO2 + 4H2O
Option 1. Our textbook suggests that if the liquid is at or above its flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. In such a case, the liquid is already evaporating sufficiently to reach the lower flammability limit in the vapor phase over the fuel surface. Can liquid […]
