which reaction occurs at the anode of a galvanic cell that has a zinc
electrode in an electrolyte with zinc ions and a copper electrode in an
electrolyte with copper ions? the reduction potential for the reduction of cu2+
= 0.34 v. the reduction potential for the reduction of zn2+ = -0.76 v.
o a. zn2+(aq) + 2e → zn(s)
o b. cu2+ (aq) + 2e i→ cu(s)
o c. cu(s) → cu2+ (aq) + 2e
o
d. zn(s) → zn2+ (aq) + 2e

The crust of earth may a- continets and ocean floors. b-continents only. c-layers of sedimentary rocks and continents. d-all of the above

Sodium sulfate dissolves as follows: na2so4(s) → 2na+(aq) + so42- (aq). how many moles of na2so4 are required to make 1.0 l of solution in which the na concentration is 0.10 m?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
