in 1951, a chemical company that manufactured fertilizer began dumping its waste in dinamata Bay.
apan The waste contained mercury that contaminated the ecosystem, making over 2.200 people
with mercury D oning Citizens suffered from high fever convulsions, psychosis, loss of consciousness
coma, and many times ending in death. Approximately 900 people died, as well as most of the birds and
somesticated animals in the area. Scientists investigating the tragedy concluded that people and an mas eating the fish had ingested mercury, which was causing the poisoning and sickness. After 12 years, the dumping was stopped

A. as elemental mercury moves through an aquatic ecosystem, it takes different chemical forms to
become methylmercury, which can then move through food chains. Explain the sequence of events
that take place.

answer: your mm

explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
