Mustard gas, a chemical weapon used in World War II and more recently in the Middle East has been shown to have to have a therapeutic index that enables it to be used as an effective agent in the chemotherapy of Hodgkin’s disease. It can be generated according to the reaction: SCl2(g) + 2C2H4(g) ====== S(CH2CH2Cl)2(g) An evacuated 2.5-liter flask at 20.0°C is filled with 0.129 mol of SCl2 and 0.296 mol C2H4. After equilibrium is established, 0.01745 mol mustard gas is present. What is the partial pressure of each gas at equilibrium? What is the equilibrium constant K at 20.0oC?
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.)

How many grams of CO2CO2 are in 46.0 LL of CO2(g)CO2(g) at 1.40 atmatm and 5∘C∘C? Express your answer to three significant figures with the appropriate units.
The reaction of solid calcium fluoride and sulfuric acid produces calcium sulfate solids and gaseous HF. The gas product is dissolved in water to form hydrofluoric acid. Fluorite ore, a source of calcium fluoride, contains 95%wt CaF2 and 5%wt SiO2. In a certain process, the ore is reacted with 93%wt aqueous sulfuric acid, supplied 15% in excess. From this, 95% of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction: HF reacts with SiO2 to produce H2SiF6 and liquid water. If 60%wt of hydrofluoric acid was formed when hydrogen fluoride (which exits the reactor) is dissolved in water, determine the amount of ore needed to produce one metric ton of acid. Report your answers to one decimal place only.
In the presence of nitric acid, UO2+ undergoes a redox process. It is converted to UO2 2+ and nitric oxide (NO) gas is produced according to the following unbalanced equation. H+(aq) +NO-(aq) +UO2+(aq) → NO(g) +UO22+(aq) +H2O If 2.55 x 102 mL NO(g) is isolated at 29°C and 1.5atm,what amount (moles) of UO2+ was used inthe reaction? (Hint :Balance the reaction by the oxidation states method.)
Volumetric analysis of the products of combustion of an unknown hydrocarbon, measured on a dry basis, gives 10.4% CO2 1.2% CO 2.8% O2, and 85.6% N2 Determine: a): the complete actual combustion equation, with coefficients of O2 and N2 separately in the reactants, b): the composition of the hydrocarbon and tell that whether such specie exists in nature. c): the percent theoretical air. Take oxygen in air as: 23.3% by mass and 21% by mole. NOTE: Do not solve this problem in tabulated form, otherwise your answer will be considered totally wrong.
The combustion of liquid ethanol (C2H5OH)(C2H5OH) produces carbon dioxide and water. After 4.63 mLmL of ethanol (density=0.789g/ml)(density=0.789g/ml) was allowed to burn in the presence of 15.50 gg of oxygen gas, 3.70 mLmL of water (density=1.00g/ml)(density=1.00g/ml) was collected. Determine the theoretical and percent yeild of h2o in the reaction.
A mixture of Al2O3(s) and CuO(s) weighing 18.371 mg was heated under H2(g) at 1 0008C to give 17.462 mg of Al2O3(s) 1 Cu(s). The other product is H2O(g). Find wt% Al2O3 in the original mixture.
Ozone is a trace atmospheric gas which plays an important role in screening the Earth from harmful ultraviolet radiation, and the abundance of ozone is commonly reported in Dobson units. Imagine a column passing up through the atmosphere. The total amount of O3 in the column divided by its cross-sectional area is reported in Dobson units with 1 Du = 0.4462 mmol m−2. What amount of O3 (in moles) is found in a column of atmosphere with a cross-sectional area of 1.00 dm2 if the abundance is 250 Dobson units (a typical midlatitude value)? In the seasonal Antarctic ozone hole, the column abundance drops below 100 Dobson units; how many moles of O3 are found in such a column of air above a 1.00 dm2 area? Most atmospheric ozone is found between 10 and 50 km above the surface of the Earth. If that ozone is spread uniformly through this portion of the atmosphere, what is the average molar concentration corresponding to (a) 250 Dobson units, (b) 100 Dobson units?
Butane, C4H10C4H10, is a component of natural gas that is used as fuel for cigarette lighters.

Heating MgSO4•7H2O at 150oC produces a different hydrate, MgSO4•XH2O. If heating 24.4 g of pure MgSO4•7H2O at 150oC were to give 17.2673 of pure MgSO4•XH2O, what is the integer value for X?
