Graphics Question

GROUPS:
I am attempting to compile separate graphics into one graphic using the "Row" command. I am making a graphic of a standard chemical reaction as it is written on paper. I am having a problem when I compile the pictures together:  the arrow and text jumble up because the window is too narrow for it all to show in its appropriate Scaled form.

If you refer to the pictures I attached to this post:
As you can see in Exhibit A the arrow and text are jumbled
In Exhibit B you can see upon widing the graphic window for the arrow and text it looks more like what I want it to look like (My goal)

In short:  How can I widen the window output of each image?  I tried to do so using "PlotRange" command for text, but it doesn't seem to allow the "PlotRange" command.  What do I do experts???
