If you want to study a Business stype degree e.g. Management, Accounting etc then maybe not; as long as they are complimented by more "academic" subjects. However, for a science degree as you intend on studying, it probably will be seen as soft. You have two strong subjects and one soft, but have to keep in mind that many people will be applying to your course with three strong subjects. So they may have an edge over you. But I'm studying Business Studies at the moment but that didn't stop three Russell Group universities (and a top 15 uni) from giving me offers... so who knows....
