A 20.0-milliliter sample of 0.200-molar Na2CO3 solution is added to 30.0 milliliters of 0.400-molar Sr(NO3)2 solution. Strontium carbonate precipitates. The concentration of strontium ion, Sr2 , in solution after reaction is

Why is nh3 classified as a polar molecule

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.

Is this correct if not can u correct me
