Commercially, compressed oxygen is sold in metal cylinders. If a 120-L cylinder is filled with oxygen to a pressure of 132 atm at 22 degree Celsius, what is the mass (in grams) of O2 present? how many liters of O2 gas at 1.00 atm and 22 degrees Celsius could the cylinder produce? (assume ideal behavior)
Please explain your step by step process
cisplatin a compound used in cancer treatment is prepared by reaction of ammonia with potassium
Write the balanced molecular, total ionic and net equations and names of the ionic compounds expected from the double replacement reaction of potassium phosphate and molybdenum(VI) chloride.
The pressure in a vessel containing methane and water at 70°C is 10 atm. At the given temperature the Henry's law constant for methane is 6.66 x 104 atm/mole fraction. Estimate the mole fraction of methane in the liquid.
Draw two equivalent resonance forms for nitric acid and three for nitrate ion. Rank the three types of nitrogen-oxygen bonds in order of length.
The arrangement of the orbitals is the same in a multielectron atom and a single-electron atom. In the Li atom, the 3s, 3p, and 3d orbitals have different energies. The He atom has one electron each in 1s and 2s orbitals.
If 1.13 x 104J of heat is added to a water sample and the temperature rises from 88.0c to its boiling point, what mass of water is in the sample?
Spattering does occur and some of the sample is lost onto the laboratory bench. Will the reported mole ratio of tin to oxygen be too high, too low, or unaffected. Explain.
A buffer is prepared by dissolving 25.0 g of sodium acetate (NaC2H3O2), in 1.20 L of a solution of 0.560 M acetic acid (HC2H3O2). Assume that the volume remains the same after dissolving the NaC2H3O2
A bottle containing 330 of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
explain the difference in boiling point between the isomers 1-chlorobutane and 2-methyl-2-chloropropane in terms of structure.
One way to do this is to mix oxygen with helium. Assume a mixture of 10.% oxygen and 90.% helium. Assuming Henry's law behavior, calculate the levels of oxygen and helium in the blood of a diver at 100 m. Assume T = 298 K.
At what temperature in Celsius gas occupy 350ml if the pressure reaches 450torr. b) Calculate the density in g / L, the following gases at STP: He, Ar, and CO2
