3.00 moles of an ideal gas at 27 degrees Celsius expands isothermally from an initial volume of 20.0dm3 to a final volume of 60.0dm3. Compute w for this process (a) for expansion against a constant external pressure of 1.00 x 105 Pa and (b) for a reversible expansion
at 80 deg c the vapor pressures of pure liquids x y z are 385 190 66 mm hg respectively. what pressure must be exerted
A 25.0 ml sample of 0.105 M HCl was titrated with 31.5 ml of NaOH. What is the concentration of the NaOH
system and show how the pH will change upon addition of 10.0 mL each of ) 0.10 M of HCl or NaOH. Use any combination of weak acid and its salt OR weak base or its salt.
the molar enthalpy of formation for nitrogen dioxide is +33.18 kj/mol. the chemical equation that corresponds to this value of (delta)Hf is
The handling of sodium bicarbonate is difficult due to the release of co2 during the adjustment of the pH, why can't other bases known be be easy to handle such as sodium hydroxide be used
If the pH probe was miscalibrated and reports the pH and reports the pH to be 1 unit higher than the true pH of the solution it is in, would the molar mass you report for the solid acid be higher than
Consider the galvanic cell with Sn2+/Sn and Ag+/Ag both prepared with NO3- as their anion and all solutions prepared at 1.0 M. What is the reduction half-reaction and does it occur at the anode or cathode? Also..what is the standard cell potential
100.0 mL of 0.400 M CoCl2(aq) is mixed with 100.0 mL of 1.600 M NaOH. Determine the moles of precipitate which form, and the molarity of each ion (including spectator ions) after the precipitation process is complete.
