You are going to complete several meteorological tests using a large weather balloon. You wish to check the temperature at 3000 meters altitude. You want to make sure the balloon will not burst before it reaches that height. Some calculations are needed. The balloon manufacturer guarantees the balloon up to 47.0 Liters in size.
Will the balloon make it to the necessary height without bursting? The temperature at ground level is 20 C. The pressure is 765 mmHg. The volume of the balloon prior to release is 30.0 Liters. It is filled with helium, which is lighter than air. For both calculations you will be using PV =nRT. Show all work, please.
1. Calculate the amount in grams of helium in the balloon. Hint remember n = moles
2. Can the balloon ascend to 3000 meters without bursting? The temperature and pressure at 3000 meters was measured at Temp = 6.0 C, Pressure = .565 atm

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
