The first-order decomposition of SO2Cl2 to sulfur dioxide gas and chlorine gas at 320°C has a half-life of 8.75 hr. If one begins with 600. mmHg of pure SO2Cl2 in a 5.00-L flask at 320°C, how long does it take for the total pressure in the flask to rise to 1.000 atm?
Determine the vapor pressure of a solution prepared by dissolving 250 g of Ethanol in 375 g of water?
One metric ton (1000 kg) of coal is required to produce 7.3 MW-hr of electrical energy. In 1993, the Thomas Hill power plant (a small, coal-fired plant supplying rural electric cooperatives) produced 7100000.0 MW-hr.
A sample of helium gas initially at 37.0 degrees C, 785 torr and 1.50L was heated to 65.0 degrees C while the volume expanded to 3.24 L. What is the final pressure in atm.
3.38 grams of nitrogen gas are mixed with excess oxygen gas. The reaction yields 6.63 grams of nitrogen monoxide. nitrogen (g) + oxygen (g) -> nitrogen monoxide (g)
If a raindrop weighs 57 mg on average and 5.1 X 10^5 raindrops fall on a lawn every minute, what mass of rain falls (in kg) on the lawn in 1.5 hours?
A cylinder of oxygen gas contains 26.4 g of O2. Another cylinder, twice the volume of the cylinder containing oxygen (and at the same conditions of pressure and temperature), contains CO2 gas.
Determine the Osmotic Pressure for the following aqueous solutions @ 25 degrees Celsius. (a.) 1.0. M Glucose, and (b.)1.0 M NaCl. Explain which solution has the greater osmotic pressure if any and why.
Question about Half life problem, We are performing an experiment using half-life =4.5 x 10^3 days labeled phenylalanine in which the five atomic hydrogens are labeled.To perform the experiment
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.
A small immersion heater is used to heat 475 mL of water from 75 degrees Fahrenheit to 195 degrees fahrenheit in 5.00 minutes.
Determine the partial pressure and total pressure of each gas in the vessel and process of reaction runs until eighty five of the Oxygen is used and the vessel get cooled to its starting or initial temperature.
C6H5NH3Cl is a chloride salt with an acidic cation. If 19 g of C6H5NH3Cl is dissolved in water to make 150 mL of solution, what is the initial molarity of the cation.
