Format matters in a chemist resume. (Chemistry) chem a precipitated solid in its suspended form or after settling or filtering [C16: from Latin praecipitāre to throw down headlong, from praeceps headlong, steep, from prae before, in front + caput head] Excursion into simple coordination chemistry: Bonding, backbonding and simple orbital schemes. According to Newton's third law, for every action force there is an equal (in size) and opposite (in direction) reaction force.Forces always come in pairs - known as "action-reaction force pairs." (e) Another student investigated the rate of a different reaction. The free response from 2016 (#6) also had the reaction quotient discussion, so I thought it wouldn’t hurt to have my class learn this.
