You already know about using word processors, spreadsheets and presentation software to create reports and presentation. Creating images to convey chemical information (such as equations and chemical structures) requires specialized software. Here are several options. You should use at least one of these as you construct material for your reports.
ChemDraw from CambringeSoft - as an OSU faculty, staff or student you can get
this full package for free and the licenseing is paid for from Technolgy
Resource Fund, and contributions from the Departments
of Chemistry and Pharmacy at OSU. This is the same drawing program
professionals use! Go to the OSU web page at:
https://softwarelist.oregonstate.edu/software/chemdraw and scroll down to ChemDraw
and follow directions to obtain permission to download and install this program.
Or (more easily) go directly to the Perkin Elmer site and follow directions from the Oregon State link area (scroll down). Licensing processes for current versions differs from earlier versions (v. 16 is fine, really).
