The lifting force of a helium balloon is equal to the difference in mass between a balloon full of air and a balloon full of less dense gas. calculate the volume and radius of a balloon needed if it is desired to have a lifting force (mass) of 1000 kg when the temperature is 290 k at 0.940 atm. the balloon is to be filled with helium. assume that air is 80 mol % n, and 20 mol % o2

Thermohaline circulation and gyres

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
