5 Stars for showing work. I think that I'm using the wrong standard reduction potentials. A galvanic (voltaic) cell consists of an electrode composed of zinc in a 1.0 M zinc ion solution and another electrode composed of gold in a 1.0 M gold(III) ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25 °C.
2) Calculate the concentration of an aqeuous solution of Ca(OH)2 pH of 12.05.
The Henry's Law constant (Kh) for O2 in water at 20 degrees C is 1.28e^-3 mol/L*atm. How many grams of O2 will dissolve in 2.00L of H2O that is in contact with pure O2 at 1.00 atm?
What is the percent ionization of a 0.186 M solution of this acid? A certain weak base has a Kb of 7.50 × 10-7. What concentration of this base will produce a pH of 10.06?
Suppose a black-body chamber is constructed from 55.8 g (one mole) of iron and heated to 500 K. Classical theory and the observations of Dulong and Petit indicate that the total energy of vibration of iron atoms is 3RT per mole.
Concentration of H 2 is observed 2.15 moles/L When the reaction N 2 (g) + 3 H 2 (g) ?? 2 NH 3 (g) comes to equilibrium. Determine the numerical value of the Kc equilibrium constant?
Assuming no heat loss to surrounding, write down the energy balance equation for the system and find out change in internal energy and final temperature.
What is the system? What is the surrounding? In what direction does the heat flow? Is the process endothermic or exothermic?
In the simulation, set the temperature of the sample gas to 304 . Click on the "Run" button and observe how the number of moles of the gas varies with an increase in the gas's volume
How many moles of N2O3 are needed so that you have 2.55 x 1024 oxygen atoms.
What characteristic H NMR absorptions would be expected in the aliphatic region for 9-hydroxyfluorene
What are the pH values if you take into account that the 8.00 mL of 0.100 M acid was first diluted with 100 mL water?
When NaOH is added to the reaction mixture, Cu(OH)2 does not immediatly precipitate. What else in the reaction mixture reacts with NaOH before Cu(OH)2 is formed?
