RODOX EXAMINATION An oxidation-reduction reaction involves the (1) sharing of electrons &n
RODOX EXAMINATION An oxidation-reduction reaction involves the (1) sharing of electrons (3) transfer of electrons (2) sharing of protons (4) transfer of protons In this reaction, CO→ 2 CO + O2 the oxidation number of carbon changes from: (1) 0 to +4 (3) +3 to 0 (2) +2 to +4 (4) +4 to +2 Which balanced equation represents a redox reaction? AgNO3 (aq) +NaCl (aq) →AgCl (s) +NaNO3 (aq) H2CO3 (aq)...

When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is 96,485 coulombs (C) and 1 ampere (A) = 1 coulomb/second (C/s) Part A...

mestion Completion Status: Why did I suggest that the secret to life is electrons and protons? A. Because redox reactions are necessary for all of the reactions in live cells and these redox reactions require both H+ and electrons B. Because electrons carry a negative charge and protons have a positive charge C. Because most (not all) cells need electron transport and H+ gradients to make ATP D. Because electrons are necessary for the electrical responses of the cell (like...
