Copper is commonly mined as an ore with a variable percent composition of copper (II) sulfide. This ore is also sometimes referred to as covellite. If a sample of the ore containing 12.5% covellite is exposed to oxygen under high temperatures, copper (II) oxide and sulfur dioxide will form. What is the yield of copper (II) oxide if 1.00 kg of the original ore is processed and the expected yield is 90%

At stp, what is the volume of 1 mole of co2?

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen

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
