Should be good, I took a similar workload this semester and last semester and it was alright, I was able to get A's in both Ochem and Physics. Although this is very professor dependent.
For reference - 1st semester - Ochem 1, physics (algebra based) 1, anatomy and pathophys, sociology, ochem lab - 16 credits
2nd - Ochem 2, physics 2, anatomy and pathophys 2, science and technical writing, ochem lab, research for credit - 20 credits
Both semesters were a full workload but neither was not manageable. Just be honest with yourself and realize you may have to sacrifice time form elsewhere in your life when the workload gets higher. I expect to do better this semester than last semester, but I unfortunately had to decrease the time I spent on some other things in order to keep up with the classes and study.
Good luck
