A 1 L sample from Tempe Town lake has a pH of 3.57. Exhaust from cars on nearby highways often mixes with rain to form HNO3. use this information to answer the following questions. 1. what is the concentration of H+ ions in the sample?
2.if it took 80 ml of 1 M NaOH to neutralize 250 ml of the acidic solution, what is the molarity of HNO3 in the sample?
3. How many miles of HNO3 are in the solution? ​

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.
