Description

When is chametz batel in a mixture before Pesach, but then assur on Pesach? If chametz is b'mashehu, how can one drink water from a lake, on Pesach, if a person dropped a bread crumb on a distant shore? Is the issur of chametz b'Pesach b'mashua biblical or rabbinic? Is the prohibition of "efshar l'sochato" dependent on "min b'mino b'mashehu"? Is "efshar l'sochato" assur only by basar b'chalav? Can one give a hechsher on food containing assur ingredients that was batel? Why is the shiur of "dam" a kezais and not a reviis? When is a reviis drunk within a "kedei acheilas pras"? Is boiled blood assur m'derabbonan or d'oraisa"? Chumash-Vayikra- one requires knowledge of a sin, to bring a karbon chattas. Aveilus also requires knowledge.
