2NH3 Using the equation above answer the following question given for items 39 to 44 that has 2.7 moles of N_2 and 8.9 moles of H_2 used. The actual yield after the production is 89.43 g. (Note: atomic number N= 14.007, H= 1.008)
what will be the final volume of the weather balloons if the pressure increases at 100 kpa *
For Items 1-3 consider the problem, A weather balloon with a volume of 2000L at a pressure of 96.3 kPa rises to an altitude of 1000m, where the atmospheric pressure is measured to be 60.8kPa. Assuming there is no change in the temperature or the amount of gas, calculate the weather balloon’s final volume
