10.0 cm3 of a gaseous hydrocarbon X were exploded with 100.0 cm^3 of oxygen (an excess). After cooling, the total volume of the gaseous mixture was 80.0 cm^3 . After treatment with KOH (aq), the volume of gas decreased to 40.0 cm^3 . All volumes were measured at the same temperature and pressure. Use this information to determine the molecular formula of X. Draw two possible structures for X.

As with any combustion reaction, the products of combusting a hydrocarbon fuel (CxHy) with oxygen (O2) are carbon dioxide (CO2) and water (H2O). A mass of 13.87 g for an unknown fuel was combusted in a reaction vessel containing an unknown amount of oxygen. At the end of the reaction, there still remained 13.80 g of the fuel as well as 0.1144 g of water and 0.2096 g of carbon dioxide. The oxygen was completely consumed during the reaction. How...

1 A pure hydrocarbon is used in bottled gas for cooking and heating. When 10 cm of the hydrocarbon is burned in 70 cm of oxygen (an excess), the final gaseous mixture contains 30 cm of carbon dioxide and 20 cm of unreacted oxygen. All gaseous volumes were measured under identical conditions. What is the formula of the hydrocarbon?

10 ml of a hydrocarbon was mixed with 70 ml of oxygen (excess) and sparked. The volume after explosion was 55 ml, and this was reduced to 35 ml by treatment with KOH solution. All volumes are measured at the same temperature and pressure. Deduce the molecular formula of the gas.

The Dumas method can be used to determine the amount of nitrogen in an organic compound. This method involves passing the compound over hot, solid CuO, where it decomposes to give N2, CO2 and H2O (g). The gaseous products are passed through a concentrated KOH solution to remove the CO2 and then through H2O. After the passage through H2O the gas contains only N2 saturated with water vapor. When a 0.253-g sample of a certain compound is treated in this way...
