When you balance a redox equation using the half-reaction method, what do you do after you write the oxidation and reduction half-reactions? OA Determine the oxidation numbers for the elements. OB. Balance the atoms and charges. Add back in any spectator ions. O D. Add the two half-reactions to show the overall redox equation. O E Use a coefficient to make the number of electrons lost equal the number of electrons gained.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
