If two poisonous elements are combined chemically, which of the following will be true of the resulting compound? the compound will be as poisonous as the elements, based on the chemical properties of the two elements. the compound will be more poisonous than the elements, based on the chemical properties of the two elements. the compound will not be poisonous, based on the chemical properties of the new substance. the compound may or may not be poisonous, depending on the chemical properties of the new substance.

Can smoke be transformed into liquid or used as energy or both?

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.
