Common oxidation states of mercury are +1 and +2. in the +1 oxidation state, mercury forms a diatomic cation. in the +2 oxidation state, mercury is a typical monatomic cation.
mercury(i) = hg2^2+
mercury(ii) = hg^2+

give formulas for the following mercury compounds.
mercury(i) bromide

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.
