When at the end of a word (e.g. хляб - bread), a voiced consonant is pronounced like its corresponding voiceless one - хляп. So, б becomes п.
When placed immediately before any voiceless consonant (e.g. общ - general), a voiced consonant is pronounced like its corresponding voiceless one - опщ. Щ is a voiceless consonant, so, the voiced consonant б becomes п.
Here are some more examples with the rest of the voiced consonants.
в - ф - молив (pencil) - молиф (molif), всеки (everybody) - фсeки (fseki)
