A gas is heated from 255 K to 284 K while its volume is increased from 24.0 L to 32.0 L by moving a large piston within a cylinder. If the original pressure was 1.08 atm, what would be the final pressure?
Calculate the fraction of atom sites that are vacant for lead at its melting temperature of 327C
Calculate the pH of the solution that is 0.600 M CH3NH2 and 0.500 M CH3NH3Cl. (Kb for CH3NH2 = 4.38 x 10-4)
how many mM of nitrogen atoms in 1g/L of (NH4)2SO4. molecular mass of (NH4)2SO4 is 132.14g/mol
You may assume that delta H and delta S are independent of temperature.
What is the mass, in milligrams, of mercury in 1.00 kg lake trout that just meets the Northern American standard of 0.50 ppm Hg?
a student in lab has 3.00 g of pure n2 in 0.541 g pure h2. the reaction happens following this equation n2g 3h2g rarr
What is the maximum work that can be obtained from a 340 L tank of compressed air at 4350 PSI
The equilibrium constant willYet another reaction has an equilibrium constant at 25 . It is an exothermic reaction, giving off quite a bit of heat while the reaction proceeds. If the temperature is raised to 200 , what will happen to the equilibri..
Using the van der Waals equation, calculate the pressure of 59.5 g of NH3 in a 5.20 L container at 47°C. The van der Waals constants for NH3 are: a = 4.17 L2xatm/mol2, b = 0.0371 L/mol.
what is the volume of 1 mole of Helium gas when the pressure is 1.47 atm and the temperature is 287 K.
If [a = 2.84 (+/-) 0.02], [b = 5.02 (+/-) 0.04], [c = 21.71 (+/-) 0.06], and [d = 9.49 (+/-) 0.04], calculate the absolute uncertainty in y if y = (a+b)/(c-d).
When M2S3 is heated in air, it is converted to MO2. A 4.000g sample of M2S3 shows a decrease in mass of .277 g when it is heated in air.
