For each of the following reactions, a) separate the reaction into its component half reactions, b) write a schematic representation of the cell in which the reaction would occur in the direction written, c) calculate the standard potential of the cell, and d) assign the polarity of each electrode under conditions that the reaction would occur as written. A) Ag + Fe3+ = Ag+ + Fe2+.
B) VO2+ + V3+ = 2VO2+.
C) Ce4+ + Fe2+ = Ce3+ + Fe3+

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

Which of the following true? a_volcanoes and earthquakes often near the plate boundaries. b_volcanoes occur whereve there are tall mountains. c_earthquakes cause volcanoes in the same location to erupt violently d_volcanoes and earthquakes occur only where plates are colliding with each other
