Consider 4.30 \rm L of a gas at 365 \rm mmHg and 20. \rm ^{\circ}C . If the container is compressed to 2.40 \rm L and the temperature is increased to 36\, \rm ^{\circ}C, what is the new pressure, P_2, inside the container? Assume no change in the amount of gas inside the cylinder.
Use the de Broglie relationship to determine the wavelengths of the following objects: an lithium atom moving at 2.5*10^5m/sUsing Heisenberg's uncertainty principle,
the energy required to melt 1.00 g of ice at 0 degrees celcius is 333 j. if one ice cube has a mass of 62.0 g and a
Consider the standard cell at 25C based on the following half-reactions. Pb^2+ + 2e^- --> Pb E=-0.13V Zn^2+ + 2e^- --> Zn E=-0.76V To the standard cell, OH-, is added to the zinc compartment causing precipitation of Zn(OH)2. After precipitation is..
