A good way to explain polarity and molecular shape is to draw lewis structures. In science exams you shouldn't just limit youself to writing answers. Sometimes pictures and equations can be extremely concise and effective ways of explaining answers. Logged cuongt Full Member Posts: 102 Mole ...
nsted酸性位具有更强的稳定性,当温度超过150oC仍然具有较强的Lewis酸吸附.催化剂表面稳定的NO物种和Lewis酸位上强的NH3吸附是催化剂催化活性增加的重要原因.%An Fe/TiO2 catalyst with uniform mesopores was synthesized using Pluronic F127 as a struc-ture-directing agent. This catalyst was used for selective...
