A mixture of 3 samples namely; p-nitro phenol (A), p-amino phenol (B) and p-nitro anisole (C) were eluted onto TLC plate coated with silica gel SiO2 as a non polar surface applying DI H2O as a polar eluant. What will be spot color that matches each substance according to the attached TLC chromatograph below, knowing that the polarity order is B (most polar) > A (moderate polar) > C (least polar)?

Which substances have the lowest melting points: ionic covalent, or metallic

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
