A 1-rm L flask is filled with 1.05 g of argon at 25 {rm ^circ C}. A sample of ethane vapor is added to the same flask until the total pressure is 1.45 atm.what is the partial pressure of argon in the flask?
1 Problem (Due Wed., Feb. 17) N-tris(hydroxymethyl)aminomethane (acronym TRIS, structure shown below) is commonly + used as a biochemical buffer. The pKa of the protonated form of TRIS (TRISH ) is 8.08. A laboratory manual has the following recipe for the preparation of 1.00L of .0500M pH 7.80 TRIS Dissolve buffer: 2.08g of TRIS (MW […]

The bright light that comes from a flash bulb is due to a quick combustion of magnesium, according to the following chemical equation: 2Mg (s) + O2(g) → 2MgO (s) If a flashbulb contains 1.3 g of Mg, what is the minimum pressure of O2 needed to burn up that magnesium? Assume the flashbulb has […]
1. The pka values of a compound with two ionizable groups are pk1=4.10 and pk2 between 7 and 10. We have 10 mL of a 1.0 M solution of this compound at a pH of 8.0.She adds 10.0 mL of 1.0 M HCL, which changes the pH to 3.20.What is pk2? 2.Histidine has ionizable groups […]
