A compound of mercury and oxygen is heated in order to decompose the compound. A 4.08 grams sample of mercury oxide upon heating gives off oxygen gas. After heating the mass of mercury metal left behind was 3.78 grams. Calculate the empirical formula of the compound My and: 1 O2 to 2 Hg ratio but I don't know if it's correct and if so if I should write it as
2HgO > 2Hg + O2 or just 2Hg + O2
Please someone who understands help.

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
