My bottle of a solution on the apex trident says it’s empty but when I look into it it still has a good amount at the bottle can I pour that into the other bottle from the same pack?
Not per the instruction of the manufacturer. The point is that once opened the reagents age, or coming from to different batches. Mixing old reagent with new one may make them not perform as wanted.
