Assume that the enthalpy of fusion of ice is 6020 j/mol and does not vary appreciably over the temperature range 270–290 k. if 1.40 mol of ice at 0°c is melted by heat supplied from surroundings at 284 k, what is the entropy change in the surroundings in j/k

The reaction below shows a system in equilibrium. how would a decrease in temperature affect this reaction? a. the rate of formation of the gases would increase. b. the equilibrium of the reaction would shift to the left. c. the equilibrium would shift to cause the gases to sublime into solids. d. the chemicals on the left would quickly form the chemical on the right.

Which molecules are more strongly attracted to one another -c3h8o molecules that make up liquid rubbing alcohol or ch4 molecules that make up methane gas

How does a coronal mass ejection (cme) affect the solar wind? a cme adds more particles to the solar wind, intensifying it. a cme blocks the solar wind, causing it to fade. a cme does not affect the solar wind but it does affect auroras. a cme increases the amount of energy in the solar wind.
