Calculate the cell potential for the following reaction that takes place in an electrochemical cell at 25°C.
Al(s) Al3+(aq, 0.115 M) Al3+(aq, 3.89 M) Al(s)
How can I find the pH and volume (mL) of 0.0411M KOH needed to reach the equivalence point in the titration of 23.4mL 0.0390M HNO2? The question doesn't give me a Ka or Kb value.
The Cl^- concentration in the water analysis given has been questioned. What concentration of Cl^- (mg/L) would make the cations and anions balance?
When you heat baking soda (NaHCO3), it breaks down into sodium carbonate powder (Na2CO3), carbon dioxide and water vapor. Write a correct thermo chemical equation and explain what it tells you about the reaction ( The enthalpy of this reaction is ..
Why was anhydrous, not wet, diethyl either used in the prepeatation and reaction of the Grignard reagent?
The coinage metals-copper, silver, and gold-crystallize in a cubic closest packed structure. Use the density of copper (8.95g/cm3) and its molar mass
Why are the standard reagents used in neutralization titrations generally strong acids and bases rather than weak acids and bases?
Why does a piece of potato break down a 100% hydrogen peroxide solution faster than lets say a 75% hydrogen peroxide and 25% water
Radical chlorination of pentane is a poor way to prepare 1-chloropentane but radical chlorination of a neopentane, (CH3)4C, is a good way to prepare neopentyl chloride
When 31.7mL of 0.235M Potassium hydroxide is required to completely neutralize 26.0mL of a HC 2 H 3 O 2 solution, calculate the molarity of the acetic acid solution.
A traveling wave is produced on a rope. The wave travels until it hits a wall and it is reflected. If the speed of the wave is 1.8 m/s and it takes 6.5 s to get back to the starting point, how long (m) is the rope. Round to two decimal places, do ..
Since the freezing point of a solution depends on the number of particles, what would you expect the freezing point of 0.1 m solutions of aqueous NaCL and BaCl2?
For cell with hydrogen and silver-silver-chloride electrodes, the cell potential was measured at 0.342V at 298K. Calculate the mean activity coefficient for HCL if the molality of the solution is 0.2 m.
