A gas is confined to a container with a massless piston at the top.A massless wire is attached to the piston. When an external pressure of 2.00 rm atm is applied to the wire, the gas compresses from 5.90 to 2.95 L. When the external pressure is increased to 2.50 rm atm, the gas further compresses from 2.95 to 2.36 L.
In a separate experiment with the same initial conditions, a pressure of 2.50 rm atm was applied to the gas, decreasing its volume from 5.90 to 2.36 L in one step.
If the final temperature was the same for both processes, what is the difference between q for the two-step process and q for the one-step process in joules?
If 3.60 mL of vinegar needs 45.0 mL of 0.135 M NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.50 qt sample of this vinegar?
Chemical reactions are typically faster when a catalyst is added. This is because... 1. Molecules are moving faster when a catalyst is added
If 2.50L of 1.25M BaCl2 added to 3.50L of 2.45 M NaCl, what is molarity of Chloride ions in final solution
Compute the number of gms of CoCl2 that would be needed to prepare the solutions:(a) 550 mL of a 1.75 M solution (b) 210 mL of a 0.0180 M solution.
Glucose Isomers, When glucose is placed in water two stereoisomers are formed, one with the new OH on the opposite side of the ring than the 6th carbon
A compound contains only carbon, hydrogen, and oxygen. Combustion of 0.01068 g of the compound yields 0.01601 g of CO2 and 0.00437 g of H2O. The molar mass of the compound is 176.1 g. What are the empirical and molecular formulas of the compound?

A sample of He gas (V = 3.0 L) at 5.6 atm and 25 °C was combined with 4.5 L of Ne gas at 3.6 atm and 25 °C in a 9.0 L flask (which was initially evacuated).
A fluoridated water supply contains F- at a concentration of 8.9 ppm. What is the maximum concentration of Mg2+ that can exist in this water supply without causing precipitation.
A solution is prepared by mixing 78.0 mL of 5.00 M HCl and 35.0 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.
Consider a solution of carbonic acid, H2CO3. (a) Calculate the H3O+ ion concentration of a 0.15 M solution of carbonic acid.
