演唱：Cedric Grotte 作词：化学之国、Cedric Grotte 作曲：化学之国 The reaction equation is still balanced It involves the number of constituent atoms If it is a redox reaction consider the valence It follows the change of oxidation number When the oxidation number rises Then it undergoes an oxidation reaction If the oxidation number drops It is a reduction reaction Balance of other chemical reactions Relating to the atoms of a compound The coefficients of the two parties are not necessarily the same Like the reaction equation of magnesium bar combustion Two moles of magnesium and one mole of oxygen But two moles of magnesium oxide are produced The balance of the equation takes into account the number of atoms Because the quantities of reactants and products are conserved Just like chemical equilibrium the reaction rate is equal It also has a certain equilibrium value Decomposition reaction is equivalent to factorization Break down a compound into simple substances It can be understood as splitting in two This reaction can only occur in compounds The disproportionation reaction is oxidation and reduction in the same molecule And the valence of one of the elements has gone up and down Because it is derived on the basis of redox reaction That is to say this reaction belongs to redox reaction The coefficients of the two parties are not necessarily the same Like the reaction equation of magnesium bar combustion Two moles of magnesium and one mole of oxygen But two moles of magnesium oxide are produced The balance of the equation takes into account the number of atoms Because the quantities of reactants and products are conserved Just like chemical equilibrium the reaction rate is equal It also has a certain equilibrium value
