A shining metal M, on burning gives a dazzling white flame and changes to a white powder N.
a) Identify Mand N.
b) Represent the above reaction in the form of a balanced chemical equation.
c) Does M undergo oxidation or reduction in this reaction? Justify.

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.
