Which solution contains the most total ions? 0.10 M NaCl
0.10 M CaCl2
0.10 M FeCl3
All three have the same number of ions because they are all 0.10 M

Which is not true regarding reaction rates? (2 points) catalysts are not used up in the reaction. catalysts speed up reactions by lowering the activation energy. reaction rates decrease as the concentration of reactants decrease. during reactions, concentrations of all reactants decrease at the same rate.
