Will a precipitate of Cu(OH)2 (Ksp = 1.6x10-19) form when 10.0 mL of 0.010 M NaOH is added to 1.00 L of a 0.010 M CuCl2 solution
The pH of human muscle fluids is 6.8. Calculate the value of H3O+ in muscle fluid at 25 degrees Celcius. The answer should be in scientific notation.
When 2.00 g of NaOH is added to 50.0 ml of 1.0 M HCl solution in a constant pressure calorimeter, the temperature increased by 13.1oC. Calculate the heat of neutralization in KJ/mol
what spontaneous reaction will occur in aqueous solution among the ions Sn4+, Sn2+, Co3+, and Co2+ ? What will be the E°cell for this reaction?
Ammonia condenses to form a liquid at -33.35C at atmospheric pressure. The density of liquid ammonia at this temperature is 0.6818g/ml. If the ammonia (0.224ml) is condensed at these temperatures, what would be its volume?
The Cd2 was displaced from EDTA by the addition of an excess of CN-. Titration of the newly freed EDTA required 23.5 mL of 0.0330 M Ca2 . What were the molarities of Cd2 and Mn2 in the original solution?
What is the balanced chemical equation for its reaction with nitric acid? Write the balanced chemical equation for its reaction with a potassium hydroxide.
what do the bond angles of water suggest about the hybridization state of the oxygen atom of water?
Measuring concentration of acetic acid and other organic acids in an aqueous solution, What analytical method would be employed to measure and determine the concentration of each acid in solution. Would this be a GC/MS analysis
The atmospheric pressur on Pluto is 3 microbars. Express this pressure in bars, kPa, atm, and torr.
When methanol, CH3OH, is dissolved in water, a nonconducting solution results. When acetic acid, CH3COOH, dissolves in water, the solution is weakly conductiong and acidic in nature. Describe what happens upon solution dissolution in the two cases..
The amount of nitrogen in an organic substance can be determined by an analytical method, called the Kjeldahl method, in which all the nitrogen in the organic substance is converted to ammoinia.
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
