A mixture of CS2 (g) and excess O2 (g) is placed in a 10.0 L reaction vessel at 100.0 degrees C and the pressure of 3.00 atm, A spark causes the CS2 to ignite, burning it completely, according to the equation:CS2 (g) + 3 O2 (g) -----> CO2 (g) + 2 SO2 (g)After reaction, the temperature returns to 100.0 degrees C, and the mixture of product gases ( CO2, SO2, and unreacted O2) is found to have a pressure of 2.40 atm. What is the partial pressure of each gas in the product mixture?
working solution so you add five spatula tips full of salt to a large test tube and then make your working solution with only 5mL of deionized water.
Consider 1.5 kg of austenite containing 1.15 wt% C, cooled to below 727 degrees Celcius (1341 degrees Farenheit).
Na3PO4 + 3AgNO3 = Ag3PO4 + 3NaNO3 How many moles of AgNO3 would be required to react with 2.0 mol of Na3PO4.
what is the solubilty of O2 at an elevation of 12, 000 ft where the atmospheric pressure is 0.657 atm? Assume the temperature is 25 degrees celsius, and that the mole fraction of O2 in air is 0.209 at both 12, 000 ft and at sea level.
SO2 present in air can be analyzed by titraion with permangante ions, as described in the equation:
how does the ability of permanganate (VII) ( when being reduce to Mn2+) to oxidize aqueous chloride , bromide or iodide ions change?
The nitrate concentration in an industrial effluent is determined using a nitrate ion selective electrode. Standards and samples are diluted 20-fold with 0.100 K2SO4 to maintain consatnt ionic strength.
A benzene-toulene solution with a mol fraction for benzene of 0.300 has a normal boiling point of 98.6 degrees Celsius. The vapor pressure of pure toulene at 98.6 degrees Celsius
When a metal was exposed to light at a frequency of 3.94× 1015 s-1, electrons were emitted with a kinetic energy of 5.80× 10-19 J. What is the maximum number of electrons that could be ejected from this metal
A sample of H½O with a mass of 46.0 grams has a temperature of -58.0 C. How many joules of energy are necessary to melt 46.0 grams of ice? (Use 2.1 J/g.C for the specific heat of ice, and 334.4 J/g for the heat of fusion of water.)
A system absorbs 192 kj of heat and the surroundings do 110 kj of work on the system. what is the change in internal energy of the system.
A 62g piece of ice at 0 degrees C is added to a sample of water at 6 degrees C. All of the ice melts and the temp of water decreases to 0 degrees C. How many grams of water were in the sample?
