this question is based on conservation of mass. Lead hydrogen arsenate, also called lead arsenate, acid lead arsenate or LA, chemical formula PBHASO4, is an inorganic insecticide. if suppose a small amount of it, enters the human's body by any means (a very minute quantity can enters via food also, if it was used as insecticide). answer the following statements with reasonable explanation also. 1) if it enters the human's body, most of lead and arsenic removed from the body via urine excretion. a small quantity of it may stay in the body. (True/False) 2) if suppose small quantity of it, stayed in the body, the amount of lead arsenate can increases with time in his body, even though the person do not exposed to it further (True/False) 3) statement 2 is against conservation of mass, since our body can not produce lead arsenate by it's own. it has to come from externally to accumulate (True/False) 4) if suppose a small quantity of it stored in liver, the size of liver increases with time due to the amount of lead and arsenic increases with time, even though the person do not exposed to it further (True/False) 5) statement 4 is wrong, since our liver can not produce these heavy metals (lead and arsenic) by it's own. these elements created in nuclear reactions which occurred during the big bang and inside the massive stars. (True/False) 6) None of the elements created in our body, our body just uses the elements from what we eat (True/False).
