Calculate the frequency (in Hz) of light necessary to move an electron in a He+ ion from the n =2 to n =4 energy level. The Rydberg constant for a helium ion is R = 4.390 x 107 m-1
The temperature in the laboratory was 25°C, and the barometric pressure was 740 mmHg. At 25°C, the vapor pressure of water is 23.8 mmHg. Calculate the equivalent mass, EM, of the unknown metal anode. The student was told the metal was oxidized to ..
A sample of gas has a volume of 35 liters and a temperature of 27 celsius. With the pressure remaining constant, the volume is raised to 50 liters. What is the new temperature
Proteins rich in disulfide bonds often require longer incubation times at higher temperatures before they denature. Why?
One liter of a buffer solution is prepared by dissolving 0.115 mol of NaNO2 and 0.070 mol of HCl in water. What is the pH of this solution? If the solution is diluted two fold with water, what is the pH?
The standard electrode potential for the reduction of Eu3+(aq) to Eu2+(aq) is ?0.43 V. Use the data in Appendix D to determine which of the following is capable of reducing Eu3+(aq) to Eu2+(aq) under standard-state conditions
To identify a diatomic gas x2 a research carried out the following experiment: She weighed an empty 1 L bulb, then filled it with the gas at 1.10 atm and 23.0 C and weighed it again. The difference in mass was 1.27 g. Identify the gas.
