Consider the reaction. MnS(s)+2HCl(aq)⟶MnCl2(aq)+H2S(g) If the small amount of MnS is combined with the small amount of HCl, what is the mass of the products? The mass of any excess reactants will also be included in this total.

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

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density
