Determine the overall cell reaction and E o cell (at 25°C) of a Zn electrode in a 1.0 M Zn(NO3)2 solution and a Sn electrode in a 1.0 M Sn(NO3)2 solution. E o (Zn2+/Zn) = −0.76 V, E o (Sn2+/Sn) = −0.14 V. What reaction occurs in the cell?

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .
