For a 0.0020 m aqueous solution of MgCl2 at 298K calculate:
a. The activity coefficients of the Mg2+ and Cl- ions in this solution
b. The mean ionic activity coefficients of these ions.
A. A student places 2.10 L of water in his dormitory room, which has the volume of 4.06 x10^4 L. He seals the room and waits for the water to evaporate. At 25 deg C, the density of water is 0.997 g/mL
Using heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following. calories to condense 135 g of steam at 100^{circ}{rm C} and to cool the liquid to 15^{circ}{rm C} (two steps)
The atmospheric pressure was measured to be0.9337 atm, the room temperature was 20.00oC. At this temperature, the vapor pressure of water is 17.50 torr -- but assume a 50% relative humidity as outlined in the procedure for this experiment.
How many grams of the element nickel are contained in 10.0g of a 10.2 wt% solution of nicke sulfate hexahydrate, NiSO4*6H2O?
Multiple choice questions in Radioactive Decay - electron emitted from the nucleus during some kinds of radioactive decay is known
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to ..
a second order reaction has rate constant .028M^-1hr^-1. initial concentration is 3.4 M. what will be the percentage remaining after a period of 24 hours?
Calculate the amount of heat needed to convert 96 g of ice at -24C to water at 28C. The specific heat capacity of H2O(s) is 2.1J/g*C.
15.73 grams of a solution containing 8.43% acetic acid, HC2H3O2, is mixed with water and titrated with a 0.523 M solution of KOH. How many milliliters of the KOH solution are required to reach the equivalence point?
what is the pH of the buffer solution and what is the ratio of acid to conjugate base in order to decrease the pH by 1.00 unit from the value calculated of the buffer solution.
Suppose that you designed a spacecraft to work by photon pressure. The sail was a completely absorbing fabric of area 1.0 km^2 and you directed a red laser beam of wavelength 650 nm on it from a base on the moon. What is the (a) force, (b) pressur..
What is the vapor pressure of a solution that contains .944 moles Ba(NO3)2 and 30 moles of H2O? The vapor pressure of pure water at the same temperature as the solution is 46 torr
