Is this chem equation balanced?

Mn2O7+14HCl → 2MnCl2(H2O)7+5Cl2 (the numbers after the elements are supposed to be sub numbers) and this is supposed to be permanganic acid and hydrochloric acid producing manganese (2) chloride and chlorine gas... Just let me know if this is right or if there are mistakes please tell me how to fix it thanks!
