The effect of mercury intake to human body should be explained when the stomach contains nitric acid instead of hydrochloric acid. Concept Introduction: One of the major issues facing the by the modern world is heavy metal poisoning. Heavy metals such as mercury, lead, arsenic etc., are naturally occurring metals. The quantity of these metals in the environment is increased due to various human activities. Combustion of coal, cement manufacture, textile industry, paint industry etc., are the various man made source of heavy metals. Among the heavy metals mercury is one of the dangerous metals. Mercury can be entered into human body through food cycle or by inhaling as mercury vapour. Intake of elemental mercury will not create much health issues. But mercury in the form of mercurous and mercuric ion will enter to the human body and creates various health issues. Memory lose, kidney problems and muscle weakness are the major health issues of mercury poisoning. When taken in excess, it can even lead to death.

Also calculate the amount of starting materials chlorobenzaldehyde and p-chloroacetophenone
required to prepare 400 mg of the given chalcone product 1, 3-bis(4-chlorophenyl)prop-2-en-1-one
molar mass ok 1,3-bis(4-Chlorophenyl) prop-2-en-1-one = 277.1591m01
number of moles= 0.400/277.15 = 0.00144 moles
2 x 0.00 144=0.00288 moves
arams of acetophenone = 0.00144 X 120.16 = 0.1739
0.1739x2=0.3469
grams of benzaldehyde = 0.00144X106.12=0.1539
0.1539x2 = 0.3069
Starting materials:
0.3469 Ox acetophenone,
0.3069 of benzaldehyde
