In an ice cream maker, why do the ingredients get colder? A) Energy is taken away from the colder ice cream maker. B) The heat moves from the ingredients to the colder ice cream maker.

For a reaction in a voltaic cell, both ΔH° and ΔS° are positive. Given the following equations for standard free energy, ΔG° = ΔH° - TΔS°; ΔG° = - nFE°.

1. Calculate the molar enthalpy of solidification (ΔHsolidification) when 10.00kJ of energy are lost as 30.00g of water are frozen at 0ºC. Remember that this value will be negative, because energy is lost when water freezes.

What did the Curies demonstrate by studying pitchblende? Uranium is not the only radioactive element. All elements are potentially radioactive. Radium can cause anemia, bone and tissue damage, and death.

The reaction below has an equilibrium constant kp=2.2*106 at 298 k. 2cof2 (g) ⇌co2 (g) + cf4 (g) calculate kp for the reaction below. cof2 (g) ⇌12co2 (g) + 12cf4 (g)

The electrical conductivities of the following 0.100 M solutions were measured in an apparatus that contained a light bulb as the indicator of conductivity. Rank the solutions in order of decreasing intensity (brightest to dimmest) of the light bulb.
