In the reaction h2so4 + 2 naoh -> na2so4 + 2h2o, an equivalence point occurs when 18.45 ml of 0.1953 m naoh is added to a 21.25 ml portion of h2so4. what is the [h2so4]?

If 90.0 grams of ethane reacted with excess chlorine, how many grams of dicarbon hexachloride would form

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.

How many liters of water can be produced from 5.0liters of butane gas at stp, assuming excess oxygen? c4h10(g) + 02(g) → co2 (e) + h2o (g)
