Calculate the bond order in the following species. Predict which of the two species in the following pairs has the higher vibrational frequency:
a) Li2 or Li2+
b) C2 or C2+
When heated, lithium reacts with nitrogen to form lithium nitride: 6Li(s) +N2(g) → 2Li3N(s)
Proceeds at a certain temperature until the partial pressures of H2O, H2, and O2 reach 0.0800 atm, 0.00500 atm, and 0.00200 atm respectively.
Consider a sealed flask with a moveable piston that contains 5.25L of O2 saturated water vapor at 25O C. The vapor pressre of water at this temperature is 23.76 mmHg. The piston is depressed at constatnt temperature so that the gas is compressed t..
the carbacation to produce 2,4,4-trimethyl-2-pentene and 2,4,4-trimethyl-1-pentene. in order to calculate the % yield, could you help with the correct balanced equation for this reaction, as i would need the moles ratio?
A balloon is partly inflated with 480 liters of helium at sea level where the atmospheric pressure is 996 mbar.The balloon ascends to a altitude of 3000 meters.
What can be said about the stoichiometric coefficients of a balanced chemical reaction AND the powers to which the concentrations are raised in the rate-law expression
What is the molarity of a solution made by dissolving 5.69 g of sodium acetate in water and diluting to 750. mL? (molar mass NaC2H3O2 is 82.0 g/mol.)
A certain substance has a heat of vaporization of 46.01 kJ/mol. At what Kelvin temperature will the vapor pressure be 3.50 times higher than it was at 351 K
The peak was assigned as a Mn-Cl stretching mode of a contaminate manganese chloride species. Why would you expect this to be an erroneous assignment? Suggest a more likely source of this IR absorption.
The reaction is between furan and maleic anhydride. Using 0.19 g of furan and 0.24 g of maleic anhydride.
