Water to a residential area is transported at a rate of 1.5 m3/s via 70-cm-internal-diameter concrete pipes with a surface roughness of 3 mm and a total length of 1500 m. In order to reduce umping power requirements, it is pro posed to line the interior surfaces of the concrete pipe with 2-cm-thick petroleum-based lining that has a surface rough ness thickness of 0.04 mm. There is a concern that the reduc tion of pipe diameter to 66 cm and...

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.
