During the lab, you measured the ph of common household items. write net brønsted equations that show the acidic or basic nature of the following substances, given the ph. for polyprotic acids, only show one proton transfer. remember that spectator ions are not included. (use the lowest possible coefficients. omit states-of-matter in your answer.) (a) native lime (calcium oxide) with a ph of 10.50

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.
