Use general chemistry rules for significant figures. 1. (12 pts) A cell is constructed to reduce the Ag+ in AgCl(s) to Ag(s) at the cathode when
current is passed through the cell. At the anode, Cu(s) is oxidized to Cu2+.
If current of 0.500 A is passed through the cell for 101 minutes, calculate the mass of
Cu(s) dissolved and mass of Ag(s) deposited. Half-cell reactions:
Cathode: AgCl(s) + e ⇌ Ag(s) + Cl–
Anode: Cu(s) ⇌ Ce2+ + 2e

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
