Determine the amount of acetic acid and sodium acetate required. The Ka of acetic acid is 1.8 X 10^-5. Show the calculations for the preparation of 100 mL of an acetic acid - sodium acetate pH 5.0 buffer using .30 M acetic acid.
Physical propoerties and intermolecular forces, What type of intermolecular forces accounts for the following differences in each case?
A flask contains a mixture of two ideal gases, A and B. Show graphically how the total pressure of the system depends on the amount of A present
Pathological consequences might ensue if various components of the regulation of signal transduction are altered inappropriately.
When ethane (C2H6) reacts with chlorine (Cl2) the main product is C2H5Cl; but other products containing Cl (chlorine), such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. In a ..
vessel is filled with .202 mol of NO and .202 mol of O3 at 366K. Find the partial pressure of each produce and the total pressure in the flask at the end of the reaction.
what is the theoretical yield of aluminum oxide if 2.40 mol of aluminum metal is exposed to 2.10 mol of oxygen
If we have a solution that contains 0.022 M Calcium and 0.014 Magnesium and we have to use potassium hydroxide to selectively precipitate one of the ions, while leaving the other ion in the solution.
Consider 25.0 g of water at 21.7°C that are mixed with 25.0 g of water at 43.3°C in a foam cup calorimeter. The equilibrium temperature reached was 30.4°C.
An unknown element, X, reacts with chlorine to form a compound with the formula XCl2. Which element is most likely to be element X?
A 180 kiln is used for vitrifying ceramics. It is currently operating at 1025 , and the pressure is 1.100 . How many moles of air molecules are within the confines of the kiln.
