If a cubic unit cell for a binary metal oxide (MxOy) has metal ions at the body position and all corner positions, and oxide ions at all the face positions, what is the oxidation state for the metal ion in the oxide?
Formic acid, HFor, has a Ka value equal to about 1.8 * 10^(-4). A student is asked to prepare a buffer having a pH of 3.60 from a 0.10 M HFor and a 0.10M NaFor solution. How many milliliters of the NaFor solution should she add to 20 ml of the 0.1..
Use the thermochemical equation that you created in question 1. (Equation from question 1 = -1420 KJ/mol)
Enough of a monoprotic acid is dissolved in water to produce a 0.0131 M solution. The pH of the resulting solution is 2.48.
Assuming that DHo and DSo hardly change with temperature, determine the temperature in K at which the spontaneity of this reaction changes.
Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.
What volume would a 0.0236-mole sample of helium gas would occupy at a temperature of 24°C and a pressure of 0.750 atm?
Consider uJT=(dT/dP)H. (this means the rate of change of Temperature divided by the rate of change of pressure at constant enthalpy)
Problem- If a buffer solution contains 4.3M C6H5COOH (ka=6.6x10^-5) and 3.3M C6H5COOK , then what is the pH of the final solution
What is the mass (in kg) of helium if it filled a square room if the room has walls that are 9.5 feet high and 9.5 long and the density of helium is 0.18 g/L
What pricing method would you advise Ricky's company to use?
Define A piece of metal weighing 5.15g at a temperature of 49.3 °C was placed in a calorimeter in 20.00 mL of DI water at 22.1 °C. Define the final equilibrium temperature was found to be 29.4 °C. Explain what is the specific heat of the metal
