En el laboratorio, se lleva a cabo un experimento para investigar los efecto de la generación de SO3, para lo cual se introducen una cierta cantidad de gramos de SO2 en un recipiente de 1 L que ya estaba previamente lleno de aire a 740 mmHg y 298K (composición molar del aire 79% N y 21% O2) ¿Qué volumen de SO2 (medido a 1000 mmHg y 30°C) será necesario para que reaccione todo el O2 que había en el recipiente?

Iknow the answer is a but i don't know why

Write two balanced equations 1. dissolving of solid sodium hydroxide in water 2. the reaction of sodium hydroxide solution with hydrochloric acid

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
