The heat capacity of the solid lead oxide is given by:Cp = 44.35 J/K/mol + 1.47*10^-3 T J/K^2 Calculate the change in enthalpy of 3.25 mol of PbO(s) if it is cooled from 750 K to 300 K at constant pressure
Why adding distioled water to the vinegar sample prior to beginning the titration does not affect the result of your determination of the molarity
When pressure is applied to a liquid, its volume decreases. Assuming that the isothermal compressibility
calculate the inimum temperature at which this process will be spontaneous under standard conditions. Assume that Delta Ho and Delta So do not vary with temperature.
equilibrium at 25C with 5.82L of an aqueous solution of N2O(aq). what is mass of N2O whic is disssolved?
Suppose some of the solid Calcium Hydroxide is inadvertently transferred along with a supernatant liquid for analysis. Will more, less, or the same amount of HCL titrant be used for analysis
what is the maximum number of grams of [Co(NH3)6]Cl3 that can be produced?
The half-life of Plutonium-239 is 24,000 years. If 10 gms are present now, how long will it take until only 10% of the original sample remains? Round your answer to the nearest 10,000th.
calculate the [OH^-] of each aqueous solution with the following [H3O^+] at 25 degrees C: a)baking soda, 1.0x10^-8 M b)orange juice, 2.0x10^-4 M c)milk, 5.0x1-^-7 M d)bleach, 4.8x10^-12 M
Determine the final temperature of the mixture. (Use 1g/mL as the density of water)
What is an indicator and explain how it is used in titration. Enumerate the criteria in choosing the indicator for a specific titration.
A fish tank holds 30.0 gal of water. Using a density of 1.0 g/mL for water, determine the number of pounds of water in the fish tank.
A scuba diver with a lung capacity of 5.2 L inhales a lungful of air at a depth of 45 m and a pressure of 5.5 atm. If the diver were to ascend to the surface (where the pressure is 1.0 atm) while holding her breath.
