Helium at 300 K and 3000 bar is fed into an empty cylinder until the pressure in the tank is equal to 1500 bar. Calculate the final temperature of the helium inside the cylinder. Assume helium to be an ideal gas with Cp=(5/2)R.
the actual yield of a reactant is 22 g and the theoreticaal yield is 25 g calculate the percentage yield
What is the molecular formula of the molecule that had an empiricial formula of C2 H4 S and a molar mass of 180.35% g/molecular.
A 55.0-{ g} piece of ice at 0.0 C is added to a sample of water at 8.0 C. All of the ice melts and the temperature of the water decreases to 0.0 C.
The structure for methyl orange in acid solution is not as simple as protonation of the amine nitrogen. In fact, protonation of one of the azo nitrogens occurs resulting in a new, conjugated system.
In chemical reactions the total number of moles of products must be the same as the total number of moles of reactants.
Neat, aliphatic, primary amines show two absorptions between 3400 to 3330 cm-1 and 3330 to 3250 cm-1 due respectively to asymmetrical and symmetrical stretch. Stretch at 3300 cm-1. Why do tertiary amines not absorb in this region of the spectrum?
The sample is placed in a drying dish (weight = 0.5000 g before the sample is added), and then placed in an oven at 104°C until all the moisture is evaporated
Three gases, hydrogen, helium, and krypton are confined in a 10.0 L vessel at a pressure of 6.00 atm. The vessel contains 4.00 moles of hydrogen, 3.00 moles of helium, and 5.00 moles of krypton.
