Standard Ag+ solution was prepared by dissolving 1.2243 g of dry AgNO3 (FW 169.87) in water in a 500.0 mL volumetric flask. A dilution was made by delivering 25.00 mL of solution with a pipet to a second 500.0 mL volumetric flask and diluting to the mark. Find the concentration of Ag+ in the dilute solution.
What is the pH of the buffer after the addition of 0.02 mol of NaOH? C)What is the pH of the buffer after the addition of 0.02 mol of HI? Express Numerically
Liquid sodium is being considered as an engine coolant. How many grams of liquid sodium (minimum) are needed to absorb 9.30 MJ of energy (in the form of heat) if the temperature of the sodium
When we extrapolate concentration dependent values to zero solute concentration, what do these extrapolated values mean physically
calculate E when 830.0 g of CH3OH(g) completely reacts at a constant temperature of 300 K and constant pressure of 0.95 atm.
The second-order reaction, 2 Mn(CO)5 Mn2(CO)10 has a rate constant equal to 3.0 x 109 M-1s-1 at 25°C. If the initial concentration of Mn(CO)5 is 1.0 x 10-5 M.
Write the overall equation for the reaction. B) Do you expect this reaction to go by an E1 or an E2 mechanism?
what would be the atmospheric pressure of MTBE in Pa If this sample were at equilibrium with atmospheric MTBE? KH = 1.7 M/atm.
The results below are from a titration lab utilizing 25mL of .1M acetic acid which was titrated with the NaOH solution of volume and molarity shown below. Please show how to get the correct pH at equivalence to compare with indicator change
A 1.30 g sample of dry ice is added to a 760 mL flask containing nitrogen gas at a temperature of 25.0 degrees Celcius and a pressure of 735 mmHg. The dry ice is allowed to sublime.
Liquids "flow" quickly as measured by the speed at which a small amount of liquid will spread itself out to form a puddle. What does this behavior imply about the speeds at which the individual liquid particles are moving relative to each other?
suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag+, Ba2+, and Mn2+. the addition of HBr causes a precipitate to form
