Compute the difference in pressure between CH4 and an ideal gas if 14.0 moles of gas are in a 6.00 litres tank at the temperature of 21.1 degree celsius . The van der Waals constants for CH4 are a =2.300 L^2 x atm/mol ^2 and b=0.0430 L/mol.
Determine the molarity of a saturated aqueous solution of NaI formed as 25degree celsius assuming that the added NaI does not add significantly to the volume of the water?
mixture(O,H) is ignited with a spark and it reacts to form (H2O)liquid water. determine the temperature of water.
A 2.30 L sample of O2(g) was collected over a liquid at a total pressure of 785 torr and 25°C. When the O2(g) was dried (vapor of that liquid removed), the gas had a volume of 1.86 L at 25°C and 785 torr.
Discuss the importance of economics as it relates to pollution prevention. Supple at least two seperate examples to augment your discussion.

Solve an equilibrium problem (using an ICE table) to calculate the pH of each solution:a solution that is 0.165M in HC 2 H 3 O 2 and 0.120M in KC 2 H 3 O 2.
The state function to describe a particle on a sphere is given as Ψ=2sin^2(?)+cos?(θ).calculate the expectation value of its angular momentum about the z-axis, energy and the square of the total angular momentum L^2.
How many mL Hydrochloric acid of 0.1 M must be added to 100 mL of a 0.2 M solution of tris base to form a buffer ( pH 7.8)?
A body consists of a right circular cone whose base is 12 in. and whose altitude is 16 in. A hole 8 in. in diameter and 4 in. deep has been drilled from the base. The axis of the hole coincides with the axis of the cone. Locate the centroid of the..
Your metropolitan area has been warned by the EPA to lower sulfur dioxide and nitrogen oxide emissions or it will lose substantial federal funding. One citizen's group calls for conservation as a means of drastically reducing electricity consumption.
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
