1. One of the first families of rockets used by the American space program was the Redstonefamily of rockets. The first Redstone rockets (in the 1950s) used B10H14 (often called decaborane)as a rocket fuel that reacts violently with liquid di-oxygen to make diboron trioxide and steam.When used as a rocket fuel, scientists carefully calculated the amount necessary so that bothcomponents ran out at the same time. (Excess fuel would be excess weight for the rocket tocarry.) If the total mass of both reactants put together is 12.0  104 kg, what was the volume ofliquid di-oxygen carried by the rockets? (Liquid di-oxygen has a density of 1.141 g/mL.)
P1A.6 The molar mass of a newly synthesized fluorocarbon was measured in a gas microbalance. is device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. The beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10Torr; for the same setting of the pivot, a balance was reached when CHF3 (M = 70.014 g mol−1) was introduced at 423.22 Torr. A repeat of the experiment with a di erent setting of the pivot required a pressure of 293.22 Torr of the uorocarbon and 427.22 Torr of the CHF3. What is the molar mass of the fluorocarbon? Suggest a molecular formula.
One type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In a hospital, pure oxygen may be delivered at 50 psi (gaugepressure) and then mixed with N2O. What volume of oxygen at 20Cand 50 psi (gauge pressure) should be mixed with 1.7 kg of N2O toget a 50%/50% mixture by volume at 20C? (a) 0.21 m3; (b) 0.27 m3;(c) 1.9 m3; (d) 100 m3

In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases. (b) Because of the rapid expansion, heat is…
How much carbon dioxide gas (mole percent) is dissolved in a bottle of sparkling water if the manufacturer used a pressure of 2.68 atm in the bottling process at 25°C? HCO2inwater=1630atm and PsatH2O=3.166kPa at 25°C. Assume xH2O=1.
For ideal gases with each of the following sets of P, V, n, and T, determine the missing number. Note that these different sets of numbers are not related to one another. Pay attention to the units. PS: Make sure that you have rearranged the equation properly. If you start from the PV=nRT form of the equation, you should never have to do anything other than dividing to isolate the variable of interest. Also, make sure you are using the proper value of R. To do so, make sure the units line up with the data that is given in the question.
Please answer the following and show the appropriate steps. Also, state which law it applies to.
