Two values (i.e., 1:2 and 1:3) of the molar ratio of the template molecule (i.e., Co(C2H3O2)2 or [Co(C2H3O2)2(z-Histidine)]) to the functional monomer (i.e., 4-VP) were employed. The numerical values of all synthesis parameters are reported in Table 1. Table 1. ...
替换不可改变的组以避免歧义。例如,C6H5C2H5 + O2 = C6H5OH + CO2 + H2O不能被平衡,但XC2H5 + O2 = XOH + CO2 + H2O可以。 不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。 例子 H2SO4 + Ca(OH)2 = CaSO4 + H2O ...
