When butane burns in oxygen, it produces carbon dioxide and water. this reaction is represented in this equation:

2c4h10 + 13o2 → 8co2 + 10h2o

this equation is balanced because there are
atoms of carbon (c),
atoms of oxygen (o), and
atoms of hydrogen (h) on each side of the equation.

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
