How did rutherford interpret the observation that only a very few of the a particles were scattered by the gold foil
Consider the reaction Fe + Sn^2+(1 x 10^-3 M) ? Fe^2+ (1.0 M) + Sn. Calculate the voltage theoretically generated by the cell.
A sample of gas is heated. During the heating process, the volume of the gas increases 1.7 times. If the initial temperature of the gas is 80degrees C. what is the final temperature of the gas?
The white precipitate obtained when cold HCl was added to an unknown solution was completely insoluble in both hot water and NH4OH
at 986°C is 0.63. A rigid cylinder at that temperature contains 1.2 atm of carbon monoxide, 0.20 atm of water vapor, 0.30 atm of carbon dioxide, and 0.27 atm of hydrogen. Is the system at equilibrium?
For an electron in a hydrogen atom, compute the most likely radius (in Angstroms) of the electron in each of the following states:
Compute the mass of an electron if the difference in the mass of 100 moles each of sodium atoms and sodium ions is 5.48002 grams?
Calculate the value of Delta G for the process- AgCl (s) Ag+(aq) + Cl-(aq) to yield a saturated solution at 298 K.
burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 4.701 °C. What is the heat capacity (calorimeter constant) of the calorimeter?
evaporated the water from NaOH extracts prior to adding acid?
Consider a container sealed with a small opening. A mixture of several gases are added to the container. Assuming the gases do not react, indicate the order that the gases escape out of the container
Important information about Galvanic cell, Consider a galvanic cell consisting of Sn wire immersed in a solution containing 10^-10 M Sn(NO3)subscript 2 and 1 M HNO3 and Ag wire immersed in 10^-2 M AgNO3 and 1 M HNO3.
The partial pressure of O2 in air at sea level is 0.21 atm. Using Henry's law, calculate the molar concentration of O2 in the surface water of a mountain lake saturated with air at 20C and an atmosphere pressure of 650 torr.
