how much heat is absorbed when 63.7g h2o at 100 c and 101.3 kpa is converted to steam at 100 c?
Two determinations of the dissolved oxygen content of a 200 mL sample of water, made five days apart, gave 5.3 ppm and 2.2 ppm of dissolved O2 respectively.
A helium balloon at a high altitude has 2.1 × 104 L of helium at 0.40 atm and -13°C. If the balloon descends to an altitude in which the atmospheric pressure is 1.00 atm and the temperature is 20°C.
2500 kg/hr of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 988 kg/hr , and the bottom stream contains 17.03 wt% benzene.
Determine what volume of HI, will be produced at the same temperature and pressure, If all the H2 and I2 are consumed?
Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 65.0L and which contains O2 gas at a pressure of 16,500kPa at 23°C.
Show all the steps in the mechanism for the following reaction, When benzene is mixed with deuterated sulfuric acid, deuterium is slowly incorporated onto the ring. Show the mechanism for this reaction and explain how this relates the sulfonation of ..
an aerosol spray can with a volume of 270 ml contains 3.2 g of propane gas propellant. what is the pressure in the can at 20 c.
2NOCl(g) → 2NO(g) + Cl2(g) ,At 450 K the rate constant is 15.4 atm-1s-1. How much time (in s) is needed for NOCl originally at a partial pressure of 46 torr to decay to 25.8 torr.
At 100 degrees C, the vapor pressure of water, methanol, and ethanol are 760, 2625, and 1694 torr, respectively. Which counpound has the highest normal boiling point.
