Use the data below from an electron impact mass spectrum of a pure compound to deduce its structure. Draw your structure in the drawing window.-You do not have to consider stereochemistry.-You do not have to explicitly draw H atoms.-In cases where there is more than one answer, just draw one.1. m/zRelative Intensity66326410049262972288327602 . m/zRelative Intensity470.7462231100293027223. m/zRelative Intensity9694941001547

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.
