HELP PLSS! A person combines 20g of hydrogen gas with some chlorine gas. They find the empirical formula of the product, and it is HCl. If they combine 120g of hydrogen gas with chlorine gas, what will the empirical formula of the product be?
1- HCl
2- Н6СІ
3- H2CI4
4- HCI4
5- Н2СІ
6- HCl2

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
