Generally each journal will have it's own style guide.
Both editorially, if they want third or first person, how they want units references given etc. and typesetting - they often supply a latex stylesheet to do this part automatically
I would just concentrate on trying to clearly and simply explain what you are trying to show. And have other people who are familiar with the field but not directly with your work review it.
There are some seriously unreadable papers because people are trying to emulate the style of classic papers, or trying to write papers as they did 100years ago. There are also a couple of journals that seem to delight in doing this.
Most journals today are on such tight margins that there is no real editorial effort to spare so they aren't going to question your split infinitives.
