Question
Nine Bottle problem (reaction of NaOH and NaBr)
(Short and simple answers is only needed)
You are using 9 different chemicals for this laboratory experiment. For each possible reaction between the 9 chemicals, predict the products and write a balanced, complete molecular equation. Look at the products you predicted for the first question. Create a three column table of a) insoluble precipitate formed, b) gas formed, and c) no reaction. Place the reactions in the appropriate column(s). Copy the resulting table into your lab notebook for use during the lab experiment.Explanation / Answer
