There are two flask connected to each other but separated by a valve. One flask is filled with the ideal gas He and has a volume of 6.50 L and a pressure of 402 torr. The other flask is filled with Ar and has a volume of 1.85 L and a pressure of 115 torr. If the valve is open and the gasses mix and assuming that the temperature is constant, what is the final total pressure?
The pressure of a sample of gas at 10.0 C increases from 700. mm Hg to 900. mm Hg. What is the new temperature?
CO exhibits an infrared absorption band at 2143 cm^-1 that is attributed to the symmetric stretching transition. Assuming this corresponds to a transition from the v=0 to v=1 vibrational quantum number
In combustion analysis, 2.00mg of vitamin C yielded 3.00mg CO2 and 0.816mg H2o. From mass spectrometry, it was found that the molecular weight of vitamin C is 176amu. Determine the mass composition of vitamin C, its empirical formula, and its molecul..
"If the crystal field splitting (Δo) is 3.44×10-19 J for a cobalt compound, what wavelength of light (in nm) is absorbed when an electron from a lower energy d orbital is promoted to a higher energy d orbital? What color will the cobalt compound a..
Explain why the salt of a weak acid, as well as the acid itself, must be present to form a bu?er solution.
A volume of 18.0 L contains a mixture of 0.250 mols N2 , 0.250 mols O2 , and an unknown quantity of He. The temperature of the mixture is 0 degrees C , and the total pressure is 1.00 atm.
provide the structures for the two products indicate two features of the spectrum (ie hydrogen ratio, peaks, classification of peak (singlet doublet etc) that would justify assigning the structure.
