The pressure of 4.57 L of an ideal gas in a flexible continer is decreased to one-third of its original pressure, and its kelvin temperature is decreased by one half. What is the final volume of the gas?
Consider the reaction 2NO2(g)--> N2O4(g). Go = -5.40 kJ at 298K. (b) Calculate delta G at 298K if partialpressures of NO2 and N2O4 are 0.36 atm and 1.60 atm
The equation for the complete combustion of ethene (C2H4) is C2H4(g) + 3 O2(g) ==> 2CO2(g) + 2H2O(g) If 2.70 mol C2H4 is reacted with 6.30 mole O2,
Given that Iron(III) oxide or ferric oxide (molar mass = 159.7 g/mol) reacts with Carbon monoxide (molar mass = 28.0 g/mol).
How many grams of oxygen would be required in the combustion of propane to produce 582 kJ of heat?
Imagine that a chemist has cyclohexanone, triphenylphosphine, butyllithium, and 2-bromobutane.
Calculate the molarity of a solution made by dissolving 0.0715 mol Na2SO4 in enough water to form 550 mL of solution.
One Way of purifying gaseous H2 is to pass it under high pressure through the holes of a metal's crystal structure. Palladium, which adopts a cubic closest packed structure
An environmental engineer analyzes a sample of air contaminated with sulfur dioxide. To a 500. mL sample of air at 700. torr and 38°C, she adds 20.00 mL of 0.01017 M aqueous iodine, which reacts as follows:
Will a precipitate of magnesium flouride form when 200.0 milliliter of 1.9x10^-3mol/Litre MgClsubnumber2 solution is added to 300.0 milliliter of 1.4x10^-2mol/Litre NaFsolution?
A white solid remains in centrifuge tube after acetone extraction-it fizzes when hydrochloric acid is added suggesting sodium carbonate was formed- How did it form? Write a balanced equation for the formation?
The EPA limit for lead in the water supply is 15 parts per billion by mass. Calculate the number of lead ions present in 1.00kg of water that is at the EPA limit for lead.
What volume of pure O2(g), collected at 27°C and 746 torr, would be generated by decomposition of 128 g of a 50.0% by mass hydrogen peroxide solution?
