a) A 7.20 L sample of air at -18 degrees Celsius has a pressure of 748 mm Hg. What will the new pressure be (in mm Hg) if the temperature is raised to 42 degrees Celsius and the volume is increases to 9.50 L?
b) A 13. 8 g sample of neon is introduced into a 4.8 L cylinder and the cylinder is cooled until the gas pressure is 1.35 atm. What is the gas temperature (in degrees Celsius) at this point?
The solubility of barium hydroxide in water at 20 degrees Celsius is 1.85g/100 water. a solution is made up of 256 mg in 35.0 g of water. is the solution saturated. if not . how much more barium hydroxide needs to be added to make a saturated solu..
a) Explain the mechanism of formation of the products. b) Explain the relative proportion of the products on the basis of their structures.
What is the density of the air in the hot-air balloon and is it less dense or more dense with the density of air at STP
Assuming the balloon could expand indefinitely and never burst, the pressure would eventually equalize causing the balloon to stop inflating. What would the volume of the balloon be when this happens?
Presume that data were collected for 10000 sets of automobile brakes. The mileage at which each set had been 80% worn through was recorded. The average was 62700 as well as the standard deviation was 10400 miles.
The air in a laboratory was measured with a barometer to be 7.40 x 100 to the 2 power mm Hg. What is the laboratory air pressure in atm?
