Calculate the pH of the solution prepared by adding 10.0 mL of 0.40 M NaOH(aq) to 50.0 mL of 0.20 M HBrO(aq). Ka for HBrO = 1.8×10−5. Temperature 25 deg C.

Which of the following describes a situation where competition between producers exists

An alloy contains 66 g of pure zinc. what is the percentage of zinc in the alloy? express your answer to two significant figures and include the appropriate units.

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.
