In science, papers are not considered publishable if they don't have any new results. There are review papers for fields, but they are usually done by a top person in the field by invitation. If your paper is simply a literature review, there's probably nothing there that can be published, no matter how well you did.

If you do have something new to contribute, there are many, many scientific journals to choose from, and your paper won't be appropriate for most of them. Try narrowing the field to the journals that you cited in your paper - those are likely to be more closely related to your subject. The journals will have submission information on their websites. Make sure it's in the right format, or they won't bother reading it. Make sure you've properly cited your sources, and that's it's written in the technical form most journals prefer. Then send it in.

But before you do so, I'd consult your professor. They could probably tell you whether or not it would be publishable and the best journal to aim for. They might be willing to help you revise it and tell you what else could be added to improve it. Very few scientists will send off a paper to a journal without first having collaborators and advisers read it over and give feedback.

Good luck!

Ask your professor. It is pretty difficult to get a paper published and you can't just submit it to everyone cause that is frowned upon. So you should try one of the low end scientific journals.
