2. In order to make a 0.75 m solution, what mass of Na3PO4 is needed to add to 550 g of water?

What is the mass of each element in a 324.8 sample of co2

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

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.
