93 The complete combustion of octane can be used as a model for the burning of gasoline: 2C8H18+25O216CO2+18H2O Assuming that this equation provides a reasonable model of the actual combustion process, what volume of air at 1.0 atm and 25°C must be taken into an engine to burn 1 gallon of gasoline? (The partial pressure of oxygen in air is 0.21 atm and the density of liquid octane is 0.70 g/mL.)
How does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?
The Mount Pinatubo volcano eruption in 1991 released an estimated 1.82 x 1013g of SO2 into the atmosphere. If the gas had an average temperature of -17.0 C and filled the troposphere, whose approximate volume is 8 x 1021L, what is the approximate partial pressure of SO2 caused by the eruption?
Pyruvic acid, HC3H3O3, is involved in cell metabolism. It can be assayed for (that is, the amount of it determined) by using a yeast enzyme. The enzyme makes the following reaction go to completion: HC3H3O3(aq)C2H4O(aq)+CO2(g) If a sample containing pyruvic acid gives 21.2 mL of carbon dioxide gas, CO2, at 349 mmHg and 30C, how many grams of pyruvic acid are there in the sample?
