What is the rate that sulfur hexafluoride would effuse through a system that allows oxygen to effuse at 22.1mL/min
Calculate the partial pressure in atmospheres of O2 in the air outside an airplane cruising at an altitude of 10 km, where the atmospheric pressure is 190.0 mmHg
An unkown metal is found to have a density of 19.3 g/cm3 and to crystallize in a body-centered cubic lattice. the edge of the unit cell is found to be 0.28864nm. What is the atomic mass of the metal? and Units?
63.0 mL of a 1.20 M solution is diluted to a volume of 208 mL. A 104-mL portion of that solution is diluted using 157 mL of water. What is the final concentration.
given an atmospheric pressure of 29.76 in Hg and a reading from a vacuum gauge 29.87 kPa, what is the pressure in the syringe?
When M2S3(s) is heated in air, it is converted to MO2(s). A 3.700-g sample of M2S3(s) shows a decrease in mass of 0.207 g when it is heated in air.
Suggest a mechanism for the hydrolysis of n-butyl bromide to n-butanol. Include the elementary steps and indicate the rate determing step
Calculate the concentration of each reactant in trials 1 through 5 after the flasks contents have been combined but before the reaction takes place.
A solution is prepared by mixing 77.0 mL of 5.00 M HCl and 11.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
Patiens suffering from repiratory disorders are often treared in oxygen tents in which the atmosphere is enriched in oxygen. What is the partial pressure of O2 in an oxygen tent consisting of 45% O2 for an atmospheric pressure of 753 mmHg?
Iodine does not have a permanent dipole and is therefore a non-polar molecule. Why Iodine does not have a permanent dipole a) electronegativities of two iodine atoms are identical b) two iodine atoms will cause partial charge separation
Write three orbital designations that would be incorrect and explain why each is incorrect. For example, 1p would be an incorrect orbital designation because there is no p sub-shell in the first orbit.
Given: 0.250L of 0.575M Pb(NO3)2 solution mixed with 0.300L of 0.822M NaOH at 25c. Determine if a precipitate forms. Calculated the concentrations to be 0.144 mol of Pb(NO3)2 and 0.247 mol of NaOH. What do I do from here
