How many moles of silver (i) sulfide are formed when a 7.20 moles of silver reacts with sulfur?

Calculate the molar mass of aluminum oxide (al2o3). express your answer to four significant figures.

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.

What is the oxidation state of each individual carbon atom in c2o42−?
